string (Timestamp format)

Output only. The time the CreateBackup request is received. If the request does not specify version_time, the version_time of the backup will be equivalent to the create_time.

string

Required for the CreateBackup operation. Name of the database from which this backup was created. This needs to be in the same instance as the backup. Values are of the form projects//instances//databases/.

enum

Output only. The database dialect information for the backup.

object (EncryptionInfo)

Output only. The encryption information for the backup.

string (Timestamp format)

Required for the CreateBackup operation. The expiration time of the backup, with microseconds granularity that must be at least 6 hours and at most 366 days from the time the CreateBackup request is processed. Once the expire_time has passed, the backup is eligible to be automatically deleted by Cloud Spanner to free the resources used by the backup.

string (Timestamp format)

Output only. The max allowed expiration time of the backup, with microseconds granularity. A backup's expiration time can be configured in multiple APIs: CreateBackup, UpdateBackup, CopyBackup. When updating or copying an existing backup, the expiration time specified must be less than Backup.max_expire_time.

string

Output only for the CreateBackup operation. Required for the UpdateBackup operation. A globally unique identifier for the backup which cannot be changed. Values are of the form projects//instances//backups/a-z*[a-z0-9] The final segment of the name must be between 2 and 60 characters in length. The backup is stored in the location(s) specified in the instance configuration of the instance containing the backup, identified by the prefix of the backup name of the form projects//instances/.

string

Output only. The names of the destination backups being created by copying this source backup. The backup names are of the form projects//instances//backups/. Referencing backups may exist in different instances. The existence of any referencing backup prevents the backup from being deleted. When the copy operation is done (either successfully completed or cancelled or the destination backup is deleted), the reference to the backup is removed.

string

Output only. The names of the restored databases that reference the backup. The database names are of the form projects//instances//databases/. Referencing databases may exist in different instances. The existence of any referencing database prevents the backup from being deleted. When a restored database from the backup enters the READY state, the reference to the backup is removed.

string (int64 format)

Output only. Size of the backup in bytes.

enum

Output only. The current state of the backup.

string (Timestamp format)

The backup will contain an externally consistent copy of the database at the timestamp specified by version_time. If version_time is not specified, the system will set version_time to the create_time of the backup.

string

Name of the backup.

string (Timestamp format)

The time the CreateBackup request was received.

string

Name of the database the backup was created from.

string (Timestamp format)

The backup contains an externally consistent copy of source_database at the timestamp specified by version_time. If the CreateBackup request did not specify version_time, the version_time of the backup is equivalent to the create_time.

integer (int32 format)

Required. The number of sessions to be created in this batch call. The API may return fewer than the requested number of sessions. If a specific number of sessions are desired, the client can make additional calls to BatchCreateSessions (adjusting session_count as necessary).

object (Session)

Parameters to be applied to each created session.

object (Session)

The freshly created sessions.

object (TransactionOptions)

Required. Options for the new transaction.

object (RequestOptions)

Common options for this request. Priority is ignored for this request. Setting the priority in this request_options struct will not do anything. To set the priority for a transaction, set it on the reads and writes that are part of this transaction instead.

object (Expr)

The condition that is associated with this binding. If the condition evaluates to true, then this binding applies to the current request. If the condition evaluates to false, then this binding does not apply to the current request. However, a different role binding might grant the same role to one or more of the principals in this binding. To learn which resources support conditions in their IAM policies, see the IAM documentation.

string

Specifies the principals requesting access for a Google Cloud resource. members can have the following values: * allUsers: A special identifier that represents anyone who is on the internet; with or without a Google account. * allAuthenticatedUsers: A special identifier that represents anyone who is authenticated with a Google account or a service account. Does not include identities that come from external identity providers (IdPs) through identity federation. * user:{emailid}: An email address that represents a specific Google account. For example, alice@example.com . * serviceAccount:{emailid}: An email address that represents a Google service account. For example, my-other-app@appspot.gserviceaccount.com. * serviceAccount:{projectid}.svc.id.goog[{namespace}/{kubernetes-sa}]: An identifier for a Kubernetes service account. For example, my-project.svc.id.goog[my-namespace/my-kubernetes-sa]. * group:{emailid}: An email address that represents a Google group. For example, admins@example.com. * domain:{domain}: The G Suite domain (primary) that represents all the users of that domain. For example, google.com or example.com. * deleted:user:{emailid}?uid={uniqueid}: An email address (plus unique identifier) representing a user that has been recently deleted. For example, alice@example.com?uid=123456789012345678901. If the user is recovered, this value reverts to user:{emailid} and the recovered user retains the role in the binding. * deleted:serviceAccount:{emailid}?uid={uniqueid}: An email address (plus unique identifier) representing a service account that has been recently deleted. For example, my-other-app@appspot.gserviceaccount.com?uid=123456789012345678901. If the service account is undeleted, this value reverts to serviceAccount:{emailid} and the undeleted service account retains the role in the binding. * deleted:group:{emailid}?uid={uniqueid}: An email address (plus unique identifier) representing a Google group that has been recently deleted. For example, admins@example.com?uid=123456789012345678901. If the group is recovered, this value reverts to group:{emailid} and the recovered group retains the role in the binding.

string

Role that is assigned to the list of members, or principals. For example, roles/viewer, roles/editor, or roles/owner.

integer (int32 format)

The node to which the link points.

string

The type of the link. For example, in Hash Joins this could be used to distinguish between the build child and the probe child, or in the case of the child being an output variable, to represent the tag associated with the output variable.

string

Only present if the child node is SCALAR and corresponds to an output variable of the parent node. The field carries the name of the output variable. For example, a TableScan operator that reads rows from a table will have child links to the SCALAR nodes representing the output variables created for each column that is read by the operator. The corresponding variable fields will be set to the variable names assigned to the columns.

object (Mutation)

The mutations to be executed when this transaction commits. All mutations are applied atomically, in the order they appear in this list.

object (RequestOptions)

Common options for this request.

boolean

If true, then statistics related to the transaction will be included in the CommitResponse. Default value is false.

object (TransactionOptions)

Execute mutations in a temporary transaction. Note that unlike commit of a previously-started transaction, commit with a temporary transaction is non-idempotent. That is, if the CommitRequest is sent to Cloud Spanner more than once (for instance, due to retries in the application, or in the transport library), it is possible that the mutations are executed more than once. If this is undesirable, use BeginTransaction and Commit instead.

string (bytes format)

Commit a previously-started transaction.

object (CommitStats)

The statistics about this Commit. Not returned by default. For more information, see CommitRequest.return_commit_stats.

string (Timestamp format)

The Cloud Spanner timestamp at which the transaction committed.

string (int64 format)

The total number of mutations for the transaction. Knowing the mutation_count value can help you maximize the number of mutations in a transaction and minimize the number of API round trips. You can also monitor this value to prevent transactions from exceeding the system limit. If the number of mutations exceeds the limit, the server returns INVALID_ARGUMENT.

string (Timestamp format)

The time at which cancellation of CopyBackup operation was received. Operations.CancelOperation starts asynchronous cancellation on a long-running operation. The server makes a best effort to cancel the operation, but success is not guaranteed. Clients can use Operations.GetOperation or other methods to check whether the cancellation succeeded or whether the operation completed despite cancellation. On successful cancellation, the operation is not deleted; instead, it becomes an operation with an Operation.error value with a google.rpc.Status.code of 1, corresponding to Code.CANCELLED.

string

The name of the backup being created through the copy operation. Values are of the form projects//instances//backups/.

object (OperationProgress)

The progress of the CopyBackup operation.

string

The name of the source backup that is being copied. Values are of the form projects//instances//backups/.

string

Required. The id of the backup copy. The backup_id appended to parent forms the full backup_uri of the form projects//instances//backups/.

Optional. The encryption configuration used to encrypt the backup. If this field is not specified, the backup will use the same encryption configuration as the source backup by default, namely encryption_type = USE_CONFIG_DEFAULT_OR_BACKUP_ENCRYPTION.

string (Timestamp format)

Required. The expiration time of the backup in microsecond granularity. The expiration time must be at least 6 hours and at most 366 days from the create_time of the source backup. Once the expire_time has passed, the backup is eligible to be automatically deleted by Cloud Spanner to free the resources used by the backup.

string

Required. The source backup to be copied. The source backup needs to be in READY state for it to be copied. Once CopyBackup is in progress, the source backup cannot be deleted or cleaned up on expiration until CopyBackup is finished. Values are of the form: projects//instances//backups/.

string (Timestamp format)

The time at which cancellation of this operation was received. Operations.CancelOperation starts asynchronous cancellation on a long-running operation. The server makes a best effort to cancel the operation, but success is not guaranteed. Clients can use Operations.GetOperation or other methods to check whether the cancellation succeeded or whether the operation completed despite cancellation. On successful cancellation, the operation is not deleted; instead, it becomes an operation with an Operation.error value with a google.rpc.Status.code of 1, corresponding to Code.CANCELLED.

string

The name of the backup being created.

object (OperationProgress)

The progress of the CreateBackup operation.

string

string (Timestamp format)

Output only. Earliest timestamp at which older versions of the data can be read. This value is continuously updated by Cloud Spanner and becomes stale the moment it is queried. If you are using this value to recover data, make sure to account for the time from the moment when the value is queried to the moment when you initiate the recovery.

object (EncryptionConfig)

Output only. For databases that are using customer managed encryption, this field contains the encryption configuration for the database. For databases that are using Google default or other types of encryption, this field is empty.

object (EncryptionInfo)

Output only. For databases that are using customer managed encryption, this field contains the encryption information for the database, such as all Cloud KMS key versions that are in use. The encryption_status' field inside of eachEncryptionInfo` is not populated. For databases that are using Google default or other types of encryption, this field is empty. This field is propagated lazily from the backend. There might be a delay from when a key version is being used and when it appears in this field.

string

Required. The name of the database. Values are of the form projects//instances//databases/, where ` is as specified in theCREATE DATABASE` statement. This name can be passed to other API methods to identify the database.

object (RestoreInfo)

Output only. Applicable only for restored databases. Contains information about the restore source.

enum

object (LocalizedString)

The name of the denominator metric. e.g. "rows".

object (LocalizedString)

The name of the numerator metric. e.g. "latency".

object (LocalizedString)

Information about this diagnostic information.

object (LocalizedString)

The metric.

boolean

Whether this message is specific only for the current metric. By default Diagnostics are shown for all metrics, regardless which metric is the currently selected metric in the UI. However occasionally a metric will generate so many messages that the resulting visual clutter becomes overwhelming. In this case setting this to true, will show the diagnostic messages for that metric only if it is the currently selected metric.

string

Output only. A Cloud KMS key version that is being used to protect the database or backup.

object (RequestOptions)

Common options for this request.

string (int64 format)

Required. A per-transaction sequence number used to identify this request. This field makes each request idempotent such that if the request is received multiple times, at most one will succeed. The sequence number must be monotonically increasing within the transaction. If a request arrives for the first time with an out-of-order sequence number, the transaction may be aborted. Replays of previously handled requests will yield the same response as the first execution.

object (Statement)

Required. The list of statements to execute in this batch. Statements are executed serially, such that the effects of statement i are visible to statement i+1. Each statement must be a DML statement. Execution stops at the first failed statement; the remaining statements are not executed. Callers must provide at least one statement.

object (TransactionSelector)

Required. The transaction to use. Must be a read-write transaction. To protect against replays, single-use transactions are not supported. The caller must either supply an existing transaction ID or begin a new transaction.

object (ResultSet)

One ResultSet for each statement in the request that ran successfully, in the same order as the statements in the request. Each ResultSet does not contain any rows. The ResultSetStats in each ResultSet contain the number of rows modified by the statement. Only the first ResultSet in the response contains valid ResultSetMetadata.

object (Status)

If all DML statements are executed successfully, the status is OK. Otherwise, the error status of the first failed statement.

map (key: string, value: object (Type))

It is not always possible for Cloud Spanner to infer the right SQL type from a JSON value. For example, values of type BYTES and values of type STRING both appear in params as JSON strings. In these cases, param_types can be used to specify the exact SQL type for some or all of the SQL statement parameters. See the definition of Type for more information about SQL types.

map (key: string, value: any)

Parameter names and values that bind to placeholders in the SQL string. A parameter placeholder consists of the @ character followed by the parameter name (for example, @firstName). Parameter names must conform to the naming requirements of identifiers as specified at https://cloud.google.com/spanner/docs/lexical#identifiers. Parameters can appear anywhere that a literal value is expected. The same parameter name can be used more than once, for example: "WHERE id > @msg_id AND id < @msg_id + 100" It is an error to execute a SQL statement with unbound parameters.

string (bytes format)

If present, results will be restricted to the specified partition previously created using PartitionQuery(). There must be an exact match for the values of fields common to this message and the PartitionQueryRequest message used to create this partition_token.

enum

Used to control the amount of debugging information returned in ResultSetStats. If partition_token is set, query_mode can only be set to QueryMode.NORMAL.

object (QueryOptions)

Query optimizer configuration to use for the given query.

object (RequestOptions)

Common options for this request.

string (bytes format)

If this request is resuming a previously interrupted SQL statement execution, resume_token should be copied from the last PartialResultSet yielded before the interruption. Doing this enables the new SQL statement execution to resume where the last one left off. The rest of the request parameters must exactly match the request that yielded this token.

string (int64 format)

A per-transaction sequence number used to identify this request. This field makes each request idempotent such that if the request is received multiple times, at most one will succeed. The sequence number must be monotonically increasing within the transaction. If a request arrives for the first time with an out-of-order sequence number, the transaction may be aborted. Replays of previously handled requests will yield the same response as the first execution. Required for DML statements. Ignored for queries.

string

Required. The SQL string.

object (TransactionSelector)

The transaction to use. For queries, if none is provided, the default is a temporary read-only transaction with strong concurrency. Standard DML statements require a read-write transaction. To protect against replays, single-use transactions are not supported. The caller must either supply an existing transaction ID or begin a new transaction. Partitioned DML requires an existing Partitioned DML transaction ID.

string

Optional. Description of the expression. This is a longer text which describes the expression, e.g. when hovered over it in a UI.

string

Textual representation of an expression in Common Expression Language syntax.

string

Optional. String indicating the location of the expression for error reporting, e.g. a file name and a position in the file.

string

Optional. Title for the expression, i.e. a short string describing its purpose. This can be used e.g. in UIs which allow to enter the expression.

string

The name of the field. For reads, this is the column name. For SQL queries, it is the column alias (e.g., "Word" in the query "SELECT 'hello' AS Word"), or the column name (e.g., "ColName" in the query "SELECT ColName FROM Table"). Some columns might have an empty name (e.g., "SELECT UPPER(ColName)"). Note that a query result can contain multiple fields with the same name.

object (Type)

The type of the field.

enum

Specifies the expiration behavior of a free instance. The default of ExpireBehavior is REMOVE_AFTER_GRACE_PERIOD. This can be modified during or after creation, and before expiration.

string (Timestamp format)

Output only. Timestamp after which the instance will either be upgraded or scheduled for deletion after a grace period. ExpireBehavior is used to choose between upgrading or scheduling the free instance for deletion. This timestamp is set during the creation of a free instance.

string (Timestamp format)

Output only. If present, the timestamp at which the free instance was upgraded to a provisioned instance.

string (bytes format)

Proto descriptors stored in the database. Contains a protobuf-serialized google.protobuf.FileDescriptorSet. For more details, see protobuffer self description.

string

A list of formatted DDL statements defining the schema of the database specified in the request.

object (GetPolicyOptions)

OPTIONAL: A GetPolicyOptions object for specifying options to GetIamPolicy.

integer (int32 format)

Optional. The maximum policy version that will be used to format the policy. Valid values are 0, 1, and 3. Requests specifying an invalid value will be rejected. Requests for policies with any conditional role bindings must specify version 3. Policies with no conditional role bindings may specify any valid value or leave the field unset. The policy in the response might use the policy version that you specified, or it might use a lower policy version. For example, if you specify version 3, but the policy has no conditional role bindings, the response uses version 1. To learn which resources support conditions in their IAM policies, see the IAM documentation.

map (key: string, value: integer (int32 format))

Cloud Labels are a flexible and lightweight mechanism for organizing cloud resources into groups that reflect a customer's organizational needs and deployment strategies. Cloud Labels can be used to filter collections of resources. They can be used to control how resource metrics are aggregated. And they can be used as arguments to policy management rules (e.g. route, firewall, load balancing, etc.). * Label keys must be between 1 and 63 characters long and must conform to the following regular expression: a-z{0,62}. * Label values must be between 0 and 63 characters long and must conform to the regular expression [a-z0-9_-]{0,63}. * No more than 64 labels can be associated with a given resource. See https://goo.gl/xmQnxf for more information on and examples of labels. If you plan to use labels in your own code, please note that additional characters may be allowed in the future. And so you are advised to use an internal label representation, such as JSON, which doesn't rely upon specific characters being disallowed. For example, representing labels as the string: name + "" + value would prove problematic if we were to allow "" in a future release.

string

Required. A unique identifier for the instance, which cannot be changed after the instance is created. Values are of the form projects//instances/a-z*[a-z0-9]. The final segment of the name must be between 2 and 64 characters in length.

integer (int32 format)

The number of nodes allocated to this instance. At most one of either node_count or processing_units should be present in the message. This may be zero in API responses for instances that are not yet in state READY. See the documentation for more information about nodes and processing units.

integer (int32 format)

The number of processing units allocated to this instance. At most one of processing_units or node_count should be present in the message. This may be zero in API responses for instances that are not yet in state READY. See the documentation for more information about nodes and processing units.

Base configuration name, e.g. projects//instanceConfigs/nam3, based on which this configuration is created. Only set for user managed configurations. base_config must refer to a configuration of type GOOGLE_MANAGED in the same project as this configuration.

enum

Output only. Whether this instance config is a Google or User Managed Configuration.

string

The name of this instance configuration as it appears in UIs.

string

etag is used for optimistic concurrency control as a way to help prevent simultaneous updates of a instance config from overwriting each other. It is strongly suggested that systems make use of the etag in the read-modify-write cycle to perform instance config updates in order to avoid race conditions: An etag is returned in the response which contains instance configs, and systems are expected to put that etag in the request to update instance config to ensure that their change will be applied to the same version of the instance config. If no etag is provided in the call to update instance config, then the existing instance config is overwritten blindly.

enum

Output only. Describes whether free instances are available to be created in this instance config.

object (KeyRangeInfo)

The list individual KeyRangeInfos.

integer (int32 format)

The total size of the list of all KeyRangeInfos. This may be larger than the number of repeated messages above. If that is the case, this number may be used to determine how many are not being shown.

boolean

For convenience all can be set to true to indicate that this KeySet matches all keys in the table or index. Note that any keys specified in keys or ranges are only yielded once.

map (key: string, value: string)

A map of arguments used when creating the localized message. Keys represent parameter names which may be used by the localized version when substituting dynamic values.

string

The canonical English version of this message. If no token is provided or the front-end has no message associated with the token, this text will be displayed as-is.

string

The token identifying the message, e.g. 'METRIC_READ_CPU'. This should be unique within the service.

enum

The aggregation function used to aggregate each key bucket

object (LocalizedString)

The category of the metric, e.g. "Activity", "Alerts", "Reads", etc.

object (DerivedMetric)

The references to numerator and denominator metrics for a derived metric.

object (LocalizedString)

The displayed label of the metric.

boolean

Whether the metric has any non-zero data.

number (float format)

The value that is considered hot for the metric. On a per metric basis hotness signals high utilization and something that might potentially be a cause for concern by the end user. hot_value is used to calibrate and scale visual color scales.

map (key: string, value: object (IndexedHotKey))

The (sparse) mapping from time index to an IndexedHotKey message, representing those time intervals for which there are hot keys.

map (key: string, value: object (IndexedKeyRangeInfos))

The (sparse) mapping from time interval index to an IndexedKeyRangeInfos message, representing those time intervals for which there are informational messages concerning key ranges.

object (LocalizedString)

Information about the metric.

object (MetricMatrix)

The data for the metric as a matrix.

object (LocalizedString)

The unit of the metric.

boolean

Whether the metric is visible to the end user.

object (MetricMatrixRow)

The rows of the matrix.

number (float format)

The columns of the row.

object (Delete)

Delete rows from a table. Succeeds whether or not the named rows were present.

object (Write)

Insert new rows in a table. If any of the rows already exist, the write or transaction fails with error ALREADY_EXISTS.

object (Write)

Like insert, except that if the row already exists, then its column values are overwritten with the ones provided. Any column values not explicitly written are preserved. When using insert_or_update, just as when using insert, all NOT NULL columns in the table must be given a value. This holds true even when the row already exists and will therefore actually be updated.

object (Write)

Like insert, except that if the row already exists, it is deleted, and the column values provided are inserted instead. Unlike insert_or_update, this means any values not explicitly written become NULL. In an interleaved table, if you create the child table with the ON DELETE CASCADE annotation, then replacing a parent row also deletes the child rows. Otherwise, you must delete the child rows before you replace the parent row.

object (Write)

Update existing rows in a table. If any of the rows does not already exist, the transaction fails with error NOT_FOUND.

boolean

If the value is false, it means the operation is still in progress. If true, the operation is completed, and either error or response is available.

object (Status)

The error result of the operation in case of failure or cancellation.

map (key: string, value: any)

Service-specific metadata associated with the operation. It typically contains progress information and common metadata such as create time. Some services might not provide such metadata. Any method that returns a long-running operation should document the metadata type, if any.

string

The server-assigned name, which is only unique within the same service that originally returns it. If you use the default HTTP mapping, the name should be a resource name ending with operations/{unique_id}.

map (key: string, value: any)

The normal response of the operation in case of success. If the original method returns no data on success, such as Delete, the response is google.protobuf.Empty. If the original method is standard Get/Create/Update, the response should be the resource. For other methods, the response should have the type XxxResponse, where Xxx is the original method name. For example, if the original method name is TakeSnapshot(), the inferred response type is TakeSnapshotResponse.

string (Timestamp format)

If set, the time at which this operation failed or was completed successfully.

integer (int32 format)

Percent completion of the operation. Values are between 0 and 100 inclusive.

string (Timestamp format)

Time the request was received.

string

Name of the restored database being optimized.

object (OperationProgress)

The progress of the post-restore optimizations.

boolean

If true, then the final value in values is chunked, and must be combined with more values from subsequent PartialResultSets to obtain a complete field value.

object (ResultSetMetadata)

Metadata about the result set, such as row type information. Only present in the first response.

string (bytes format)

Streaming calls might be interrupted for a variety of reasons, such as TCP connection loss. If this occurs, the stream of results can be resumed by re-sending the original request and including resume_token. Note that executing any other transaction in the same session invalidates the token.

object (ResultSetStats)

Query plan and execution statistics for the statement that produced this streaming result set. These can be requested by setting ExecuteSqlRequest.query_mode and are sent only once with the last response in the stream. This field will also be present in the last response for DML statements.

any

A streamed result set consists of a stream of values, which might be split into many PartialResultSet messages to accommodate large rows and/or large values. Every N complete values defines a row, where N is equal to the number of entries in metadata.row_type.fields. Most values are encoded based on type as described here. It is possible that the last value in values is "chunked", meaning that the rest of the value is sent in subsequent PartialResultSet(s). This is denoted by the chunked_value field. Two or more chunked values can be merged to form a complete value as follows: * bool/number/null: cannot be chunked * string: concatenate the strings * list: concatenate the lists. If the last element in a list is a string, list, or object, merge it with the first element in the next list by applying these rules recursively. * object: concatenate the (field name, field value) pairs. If a field name is duplicated, then apply these rules recursively to merge the field values. Some examples of merging: # Strings are concatenated. "foo", "bar" => "foobar" # Lists of non-strings are concatenated. [2, 3], [4] => [2, 3, 4] # Lists are concatenated, but the last and first elements are merged # because they are strings. ["a", "b"], ["c", "d"] => ["a", "bc", "d"] # Lists are concatenated, but the last and first elements are merged # because they are lists. Recursively, the last and first elements # of the inner lists are merged because they are strings. ["a", ["b", "c"]], [["d"], "e"] => ["a", ["b", "cd"], "e"] # Non-overlapping object fields are combined. {"a": "1"}, {"b": "2"} => {"a": "1", "b": 2"} # Overlapping object fields are merged. {"a": "1"}, {"a": "2"} => {"a": "12"} # Examples of merging objects containing lists of strings. {"a": ["1"]}, {"a": ["2"]} => {"a": ["12"]} For a more complete example, suppose a streaming SQL query is yielding a result set whose rows contain a single string field. The following PartialResultSets might be yielded: { "metadata": { ... } "values": ["Hello", "W"] "chunked_value": true "resume_token": "Af65..." } { "values": ["orl"] "chunked_value": true } { "values": ["d"] "resume_token": "Zx1B..." } This sequence of PartialResultSets encodes two rows, one containing the field value "Hello", and a second containing the field value "World" = "W" + "orl" + "d". Not all PartialResultSets contain a resume_token. Execution can only be resumed from a previously yielded resume_token. For the above sequence of PartialResultSets, resuming the query with "resume_token": "Af65..." will yield results from the PartialResultSet with value ["orl"].

string (bytes format)

This token can be passed to Read, StreamingRead, ExecuteSql, or ExecuteStreamingSql requests to restrict the results to those identified by this partition token.

string (int64 format)

Note: This hint is currently ignored by PartitionQuery and PartitionRead requests. The desired maximum number of partitions to return. For example, this may be set to the number of workers available. The default for this option is currently 10,000. The maximum value is currently 200,000. This is only a hint. The actual number of partitions returned may be smaller or larger than this maximum count request.

string (int64 format)

Note: This hint is currently ignored by PartitionQuery and PartitionRead requests. The desired data size for each partition generated. The default for this option is currently 1 GiB. This is only a hint. The actual size of each partition may be smaller or larger than this size request.

map (key: string, value: object (Type))

It is not always possible for Cloud Spanner to infer the right SQL type from a JSON value. For example, values of type BYTES and values of type STRING both appear in params as JSON strings. In these cases, param_types can be used to specify the exact SQL type for some or all of the SQL query parameters. See the definition of Type for more information about SQL types.

map (key: string, value: any)

Parameter names and values that bind to placeholders in the SQL string. A parameter placeholder consists of the @ character followed by the parameter name (for example, @firstName). Parameter names can contain letters, numbers, and underscores. Parameters can appear anywhere that a literal value is expected. The same parameter name can be used more than once, for example: "WHERE id > @msg_id AND id < @msg_id + 100" It is an error to execute a SQL statement with unbound parameters.

object (PartitionOptions)

Additional options that affect how many partitions are created.

string

Required. The query request to generate partitions for. The request will fail if the query is not root partitionable. The query plan of a root partitionable query has a single distributed union operator. A distributed union operator conceptually divides one or more tables into multiple splits, remotely evaluates a subquery independently on each split, and then unions all results. This must not contain DML commands, such as INSERT, UPDATE, or DELETE. Use ExecuteStreamingSql with a PartitionedDml transaction for large, partition-friendly DML operations.

object (TransactionSelector)

Read only snapshot transactions are supported, read/write and single use transactions are not.

string

The columns of table to be returned for each row matching this request.

string

If non-empty, the name of an index on table. This index is used instead of the table primary key when interpreting key_set and sorting result rows. See key_set for further information.

object (KeySet)

Required. key_set identifies the rows to be yielded. key_set names the primary keys of the rows in table to be yielded, unless index is present. If index is present, then key_set instead names index keys in index. It is not an error for the key_set to name rows that do not exist in the database. Read yields nothing for nonexistent rows.

object (PartitionOptions)

Additional options that affect how many partitions are created.

string

Required. The name of the table in the database to be read.

object (TransactionSelector)

Read only snapshot transactions are supported, read/write and single use transactions are not.

object (Partition)

Partitions created by this request.

object (Transaction)

Transaction created by this request.

object (ChildLink)

List of child node indexes and their relationship to this parent.

string

The display name for the node.

map (key: string, value: any)

The execution statistics associated with the node, contained in a group of key-value pairs. Only present if the plan was returned as a result of a profile query. For example, number of executions, number of rows/time per execution etc.

integer (int32 format)

The PlanNode's index in node list.

enum

Used to determine the type of node. May be needed for visualizing different kinds of nodes differently. For example, If the node is a SCALAR node, it will have a condensed representation which can be used to directly embed a description of the node in its parent.

map (key: string, value: any)

Attributes relevant to the node contained in a group of key-value pairs. For example, a Parameter Reference node could have the following information in its metadata: { "parameter_reference": "param1", "parameter_type": "array" }

object (ShortRepresentation)

Condensed representation for SCALAR nodes.

object (Binding)

Associates a list of members, or principals, with a role. Optionally, may specify a condition that determines how and when the bindings are applied. Each of the bindings must contain at least one principal. The bindings in a Policy can refer to up to 1,500 principals; up to 250 of these principals can be Google groups. Each occurrence of a principal counts towards these limits. For example, if the bindings grant 50 different roles to user:alice@example.com, and not to any other principal, then you can add another 1,450 principals to the bindings in the Policy.

string (bytes format)

etag is used for optimistic concurrency control as a way to help prevent simultaneous updates of a policy from overwriting each other. It is strongly suggested that systems make use of the etag in the read-modify-write cycle to perform policy updates in order to avoid race conditions: An etag is returned in the response to getIamPolicy, and systems are expected to put that etag in the request to setIamPolicy to ensure that their change will be applied to the same version of the policy. Important: If you use IAM Conditions, you must include the etag field whenever you call setIamPolicy. If you omit this field, then IAM allows you to overwrite a version 3 policy with a version 1 policy, and all of the conditions in the version 3 policy are lost.

integer (int32 format)

Specifies the format of the policy. Valid values are 0, 1, and 3. Requests that specify an invalid value are rejected. Any operation that affects conditional role bindings must specify version 3. This requirement applies to the following operations: * Getting a policy that includes a conditional role binding * Adding a conditional role binding to a policy * Changing a conditional role binding in a policy * Removing any role binding, with or without a condition, from a policy that includes conditions Important: If you use IAM Conditions, you must include the etag field whenever you call setIamPolicy. If you omit this field, then IAM allows you to overwrite a version 3 policy with a version 1 policy, and all of the conditions in the version 3 policy are lost. If a policy does not include any conditions, operations on that policy may specify any valid version or leave the field unset. To learn which resources support conditions in their IAM policies, see the IAM documentation.

boolean

Whether this corresponds to a data_source name.

integer (int32 format)

The depth in the prefix hierarchy.

integer (int32 format)

The index of the end key bucket of the range that this node spans.

integer (int32 format)

The index of the start key bucket of the range that this node spans.

string

The string represented by the prefix node.

string

An option to control the selection of optimizer statistics package. This parameter allows individual queries to use a different query optimizer statistics package. Specifying latest as a value instructs Cloud Spanner to use the latest generated statistics package. If not specified, Cloud Spanner uses the statistics package set at the database level options, or the latest package if the database option is not set. The statistics package requested by the query has to be exempt from garbage collection. This can be achieved with the following DDL statement: ALTER STATISTICS SET OPTIONS (allow_gc=false) The list of available statistics packages can be queried from INFORMATION_SCHEMA.SPANNER_STATISTICS. Executing a SQL statement with an invalid optimizer statistics package or with a statistics package that allows garbage collection fails with an INVALID_ARGUMENT error.

string

An option to control the selection of optimizer version. This parameter allows individual queries to pick different query optimizer versions. Specifying latest as a value instructs Cloud Spanner to use the latest supported query optimizer version. If not specified, Cloud Spanner uses the optimizer version set at the database level options. Any other positive integer (from the list of supported optimizer versions) overrides the default optimizer version for query execution. The list of supported optimizer versions can be queried from SPANNER_SYS.SUPPORTED_OPTIMIZER_VERSIONS. Executing a SQL statement with an invalid optimizer version fails with an INVALID_ARGUMENT error. See https://cloud.google.com/spanner/docs/query-optimizer/manage-query-optimizer for more information on managing the query optimizer. The optimizer_version statement hint has precedence over this setting.

object (PlanNode)

The nodes in the query plan. Plan nodes are returned in pre-order starting with the plan root. Each PlanNode's id corresponds to its index in plan_nodes.

string (Duration format)

Executes all reads at a timestamp that is exact_staleness old. The timestamp is chosen soon after the read is started. Guarantees that all writes that have committed more than the specified number of seconds ago are visible. Because Cloud Spanner chooses the exact timestamp, this mode works even if the client's local clock is substantially skewed from Cloud Spanner commit timestamps. Useful for reading at nearby replicas without the distributed timestamp negotiation overhead of max_staleness.

string (Duration format)

Read data at a timestamp >= NOW - max_staleness seconds. Guarantees that all writes that have committed more than the specified number of seconds ago are visible. Because Cloud Spanner chooses the exact timestamp, this mode works even if the client's local clock is substantially skewed from Cloud Spanner commit timestamps. Useful for reading the freshest data available at a nearby replica, while bounding the possible staleness if the local replica has fallen behind. Note that this option can only be used in single-use transactions.

string (Timestamp format)

Executes all reads at a timestamp >= min_read_timestamp. This is useful for requesting fresher data than some previous read, or data that is fresh enough to observe the effects of some previously committed transaction whose timestamp is known. Note that this option can only be used in single-use transactions. A timestamp in RFC3339 UTC \"Zulu\" format, accurate to nanoseconds. Example: "2014-10-02T15:01:23.045123456Z".

string (Timestamp format)

Executes all reads at the given timestamp. Unlike other modes, reads at a specific timestamp are repeatable; the same read at the same timestamp always returns the same data. If the timestamp is in the future, the read will block until the specified timestamp, modulo the read's deadline. Useful for large scale consistent reads such as mapreduces, or for coordinating many reads against a consistent snapshot of the data. A timestamp in RFC3339 UTC \"Zulu\" format, accurate to nanoseconds. Example: "2014-10-02T15:01:23.045123456Z".

boolean

If true, the Cloud Spanner-selected read timestamp is included in the Transaction message that describes the transaction.

boolean

Read at a timestamp where all previously committed transactions are visible.

string

Required. The columns of table to be returned for each row matching this request.

string

If non-empty, the name of an index on table. This index is used instead of the table primary key when interpreting key_set and sorting result rows. See key_set for further information.

object (KeySet)

Required. key_set identifies the rows to be yielded. key_set names the primary keys of the rows in table to be yielded, unless index is present. If index is present, then key_set instead names index keys in index. If the partition_token field is empty, rows are yielded in table primary key order (if index is empty) or index key order (if index is non-empty). If the partition_token field is not empty, rows will be yielded in an unspecified order. It is not an error for the key_set to name rows that do not exist in the database. Read yields nothing for nonexistent rows.

string (int64 format)

If greater than zero, only the first limit rows are yielded. If limit is zero, the default is no limit. A limit cannot be specified if partition_token is set.

string (bytes format)

If present, results will be restricted to the specified partition previously created using PartitionRead(). There must be an exact match for the values of fields common to this message and the PartitionReadRequest message used to create this partition_token.

object (RequestOptions)

Common options for this request.

string (bytes format)

If this request is resuming a previously interrupted read, resume_token should be copied from the last PartialResultSet yielded before the interruption. Doing this enables the new read to resume where the last read left off. The rest of the request parameters must exactly match the request that yielded this token.

string

Required. The name of the table in the database to be read.

object (TransactionSelector)

The transaction to use. If none is provided, the default is a temporary read-only transaction with strong concurrency.

enum

string

The location of the serving resources, e.g. "us-central1".

enum

The type of replica.

enum

Priority for the request.

string

A per-request tag which can be applied to queries or reads, used for statistics collection. Both request_tag and transaction_tag can be specified for a read or query that belongs to a transaction. This field is ignored for requests where it's not applicable (e.g. CommitRequest). Legal characters for request_tag values are all printable characters (ASCII 32 - 126) and the length of a request_tag is limited to 50 characters. Values that exceed this limit are truncated. Any leading underscore (_) characters will be removed from the string.

string

A tag used for statistics collection about this transaction. Both request_tag and transaction_tag can be specified for a read or query that belongs to a transaction. The value of transaction_tag should be the same for all requests belonging to the same transaction. If this request doesn't belong to any transaction, transaction_tag will be ignored. Legal characters for transaction_tag values are all printable characters (ASCII 32 - 126) and the length of a transaction_tag is limited to 50 characters. Values that exceed this limit are truncated. Any leading underscore (_) characters will be removed from the string.

enum

Required. The encryption type of the restored database.

string

Optional. The Cloud KMS key that will be used to encrypt/decrypt the restored database. This field should be set only when encryption_type is CUSTOMER_MANAGED_ENCRYPTION. Values are of the form projects//locations//keyRings//cryptoKeys/.

object (BackupInfo)

Information about the backup used to restore the database.

string (Timestamp format)

The time at which cancellation of this operation was received. Operations.CancelOperation starts asynchronous cancellation on a long-running operation. The server makes a best effort to cancel the operation, but success is not guaranteed. Clients can use Operations.GetOperation or other methods to check whether the cancellation succeeded or whether the operation completed despite cancellation. On successful cancellation, the operation is not deleted; instead, it becomes an operation with an Operation.error value with a google.rpc.Status.code of 1, corresponding to Code.CANCELLED.

string

Name of the database being created and restored to.

string

If exists, the name of the long-running operation that will be used to track the post-restore optimization process to optimize the performance of the restored database, and remove the dependency on the restore source. The name is of the form projects//instances//databases//operations/ where the is the name of database being created and restored to. The metadata type of the long-running operation is OptimizeRestoredDatabaseMetadata. This long-running operation will be automatically created by the system after the RestoreDatabase long-running operation completes successfully. This operation will not be created if the restore was not successful.

object (OperationProgress)

The progress of the RestoreDatabase operation.

enum

The type of the restore source.

string

Name of the backup from which to restore. Values are of the form projects//instances//backups/.

string

Required. The id of the database to create and restore to. This database must not already exist. The database_id appended to parent forms the full database name of the form projects//instances//databases/.

object (RestoreDatabaseEncryptionConfig)

Optional. An encryption configuration describing the encryption type and key resources in Cloud KMS used to encrypt/decrypt the database to restore to. If this field is not specified, the restored database will use the same encryption configuration as the backup by default, namely encryption_type = USE_CONFIG_DEFAULT_OR_BACKUP_ENCRYPTION.

object (BackupInfo)

Information about the backup used to restore the database. The backup may no longer exist.

enum

The type of the restore source.

object (ResultSetMetadata)

Metadata about the result set, such as row type information.

array

Each element in rows is a row whose format is defined by metadata.row_type. The ith element in each row matches the ith field in metadata.row_type. Elements are encoded based on type as described here.

object (ResultSetStats)

Query plan and execution statistics for the SQL statement that produced this result set. These can be requested by setting ExecuteSqlRequest.query_mode. DML statements always produce stats containing the number of rows modified, unless executed using the ExecuteSqlRequest.QueryMode.PLAN ExecuteSqlRequest.query_mode. Other fields may or may not be populated, based on the ExecuteSqlRequest.query_mode.

object (StructType)

Indicates the field names and types for the rows in the result set. For example, a SQL query like "SELECT UserId, UserName FROM Users" could return a row_type value like: "fields": [ { "name": "UserId", "type": { "code": "INT64" } }, { "name": "UserName", "type": { "code": "STRING" } }, ]

object (Transaction)

If the read or SQL query began a transaction as a side-effect, the information about the new transaction is yielded here.

object (StructType)

A SQL query can be parameterized. In PLAN mode, these parameters can be undeclared. This indicates the field names and types for those undeclared parameters in the SQL query. For example, a SQL query like "SELECT * FROM Users where UserId = @userId and UserName = @userName " could return a undeclared_parameters value like: "fields": [ { "name": "UserId", "type": { "code": "INT64" } }, { "name": "UserName", "type": { "code": "STRING" } }, ]

object (QueryPlan)

QueryPlan for the query associated with this result.

map (key: string, value: any)

Aggregated statistics from the execution of the query. Only present when the query is profiled. For example, a query could return the statistics as follows: { "rows_returned": "3", "elapsed_time": "1.22 secs", "cpu_time": "1.19 secs" }

string (int64 format)

Standard DML returns an exact count of rows that were modified.

string (int64 format)

Partitioned DML does not offer exactly-once semantics, so it returns a lower bound of the rows modified.

string (bytes format)

Required. The transaction to roll back.

map (key: string, value: any)

Additional information provided by the implementer.

string (Timestamp format)

The upper bound for when the scan is defined.

See https://goo.gl/xmQnxf for more information on and examples of labels.

string

Output only. The name of the session. This is always system-assigned.

object (Policy)

REQUIRED: The complete policy to be applied to the resource. The size of the policy is limited to a few 10s of KB. An empty policy is a valid policy but certain Google Cloud services (such as Projects) might reject them.

string

A string representation of the expression subtree rooted at this node.

map (key: string, value: integer (int32 format))

A mapping of (subquery variable name) -> (subquery node id) for cases where the description string of this node references a SCALAR subquery contained in the expression subtree rooted at this node. The referenced SCALAR subquery may not necessarily be a direct child of this node.

map (key: string, value: object (Type))

It is not always possible for Cloud Spanner to infer the right SQL type from a JSON value. For example, values of type BYTES and values of type STRING both appear in params as JSON strings. In these cases, param_types can be used to specify the exact SQL type for some or all of the SQL statement parameters. See the definition of Type for more information about SQL types.

map (key: string, value: any)

Parameter names and values that bind to placeholders in the DML string. A parameter placeholder consists of the @ character followed by the parameter name (for example, @firstName). Parameter names can contain letters, numbers, and underscores. Parameters can appear anywhere that a literal value is expected. The same parameter name can be used more than once, for example: "WHERE id > @msg_id AND id < @msg_id + 100" It is an error to execute a SQL statement with unbound parameters.

string

Required. The DML string.

integer (int32 format)

The status code, which should be an enum value of google.rpc.Code.

object

A list of messages that carry the error details. There is a common set of message types for APIs to use.

string

A developer-facing error message, which should be in English. Any user-facing error message should be localized and sent in the google.rpc.Status.details field, or localized by the client.

object (Field)

The list of fields that make up this struct. Order is significant, because values of this struct type are represented as lists, where the order of field values matches the order of fields in the StructType. In turn, the order of fields matches the order of columns in a read request, or the order of fields in the SELECT clause of a query.

string

REQUIRED: The set of permissions to check for 'resource'. Permissions with wildcards (such as '', 'spanner.', 'spanner.instances.*') are not allowed.

string

A subset of TestPermissionsRequest.permissions that the caller is allowed.

string (bytes format)

id may be used to identify the transaction in subsequent Read, ExecuteSql, Commit, or Rollback calls. Single-use read-only transactions do not have IDs, because single-use transactions do not support multiple requests.

string (Timestamp format)

For snapshot read-only transactions, the read timestamp chosen for the transaction. Not returned by default: see TransactionOptions.ReadOnly.return_read_timestamp. A timestamp in RFC3339 UTC \"Zulu\" format, accurate to nanoseconds. Example: "2014-10-02T15:01:23.045123456Z".

object (PartitionedDml)

Partitioned DML transaction. Authorization to begin a Partitioned DML transaction requires spanner.databases.beginPartitionedDmlTransaction permission on the session resource.

object (ReadOnly)

Transaction will not write. Authorization to begin a read-only transaction requires spanner.databases.beginReadOnlyTransaction permission on the session resource.

object (ReadWrite)

Transaction may write. Authorization to begin a read-write transaction requires spanner.databases.beginOrRollbackReadWriteTransaction permission on the session resource.

object (TransactionOptions)

Begin a new transaction and execute this read or SQL query in it. The transaction ID of the new transaction is returned in ResultSetMetadata.transaction, which is a Transaction.

string (bytes format)

Execute the read or SQL query in a previously-started transaction.

object (TransactionOptions)

Execute the read or SQL query in a temporary transaction. This is the most efficient way to execute a transaction that consists of a single SQL query.

object (Type)

If code == ARRAY, then array_element_type is the type of the array elements.

enum

Required. The TypeCode for this type.

string

If code == PROTO or code == ENUM, then proto_type_fqn is the fully qualified name of the proto type representing the proto/enum definition.

object (StructType)

If code == STRUCT, then struct_type provides type information for the struct's fields.

enum

The TypeAnnotationCode that disambiguates SQL type that Spanner will use to represent values of this type during query processing. This is necessary for some type codes because a single TypeCode can be mapped to different SQL types depending on the SQL dialect. type_annotation typically is not needed to process the content of a value (it doesn't affect serialization) and clients can ignore it on the read path.

string (Timestamp format)

Reports the commit timestamps of all statements that have succeeded so far, where commit_timestamps[i] is the commit timestamp for the statement statements[i].

string

The database being modified.

object (OperationProgress)

The progress of the UpdateDatabaseDdl operations. Currently, only index creation statements will have a continuously updating progress. For non-index creation statements, progress[i] will have start time and end time populated with commit timestamp of operation, as well as a progress of 100% once the operation has completed. progress[i] is the operation progress for statements[i].

string

For an update this list contains all the statements. For an individual statement, this list contains only that statement.

boolean

Output only. When true, indicates that the operation is throttled e.g due to resource constraints. When resources become available the operation will resume and this field will be false again.

string

If empty, the new update request is assigned an automatically-generated operation ID. Otherwise, operation_id is used to construct the name of the resulting Operation. Specifying an explicit operation ID simplifies determining whether the statements were executed in the event that the UpdateDatabaseDdl call is replayed, or the return value is otherwise lost: the database and operation_id fields can be combined to form the name of the resulting longrunning.Operation: /operations/. operation_id should be unique within the database, and must be a valid identifier: a-z*. Note that automatically-generated operation IDs always begin with an underscore. If the named operation already exists, UpdateDatabaseDdl returns ALREADY_EXISTS.

string (bytes format)

Optional. Proto descriptors used by CREATE/ALTER PROTO BUNDLE statements. Contains a protobuf-serialized google.protobuf.FileDescriptorSet. To generate it, install and run protoc with --include_imports and --descriptor_set_out. For example, to generate for moon/shot/app.proto, run """ $protoc --proto_path=/app_path --proto_path=/lib_path \ --include_imports \ --descriptor_set_out=descriptors.data \ moon/shot/app.proto """ For more details, see protobuffer self description.

string

Required. DDL statements to be applied to the database.

string (Timestamp format)

The time at which this operation was cancelled.

object (InstanceConfig)

The desired instance config after updating.

object (InstanceOperationProgress)

The progress of the UpdateInstanceConfig operation.

object (InstanceConfig)

Required. The user instance config to update, which must always include the instance config name. Otherwise, only fields mentioned in update_mask need be included. To prevent conflicts of concurrent updates, etag can be used.

string (FieldMask format)

Required. A mask specifying which fields in InstanceConfig should be updated. The field mask must always be specified; this prevents any future fields in InstanceConfig from being erased accidentally by clients that do not know about them. Only display_name and labels can be updated.

boolean

An option to validate, but not actually execute, a request, and provide the same response.

string (Timestamp format)

The time at which this operation was cancelled. If set, this operation is in the process of undoing itself (which is guaranteed to succeed) and cannot be cancelled again.

string (Timestamp format)

The time at which this operation failed or was completed successfully.

object (Instance)

The desired end state of the update.

string (Timestamp format)

The time at which UpdateInstance request was received.

string (FieldMask format)

Required. A mask specifying which fields in Instance should be updated. The field mask must always be specified; this prevents any future fields in Instance from being erased accidentally by clients that do not know about them.

object (Instance)

Required. The instance to update, which must always include the instance name. Otherwise, only fields mentioned in field_mask need be included.

string

The token signifying the end of a data_source.

string

The token delimiting a datasource name from the rest of a key in a data_source.

object (DiagnosticMessage)

The list of messages (info, alerts, ...)

string

We discretize the entire keyspace into buckets. Assuming each bucket has an inclusive keyrange and covers keys from k(i) ... k(n). In this case k(n) would be an end key for a given range. end_key_string is the collection of all such end keys

boolean

Whether this scan contains PII.

string

Keys of key ranges that contribute significantly to a given metric Can be thought of as heavy hitters.

string

The token delimiting the key prefixes.

enum

The unit for the key: e.g. 'key' or 'chunk'.

object (Metric)

The list of data objects for each metric.

object (PrefixNode)

The list of extracted key prefix nodes used in the key prefix hierarchy.

string

The names of the columns in table to be written. The list of columns must contain enough columns to allow Cloud Spanner to derive values for all primary key columns in the row(s) to be modified.

string

Required. The table whose rows will be written.

array

The values to be written. values can contain more than one list of values. If it does, then multiple rows are written, one for each entry in values. Each list in values must have exactly as many entries as there are entries in columns above. Sending multiple lists is equivalent to sending multiple Mutations, each containing one values entry and repeating table and columns. Individual values in each list are encoded as described here.
