#copy_backup

def copy_backup(request, options = nil) -> ::Gapic::Operation
def copy_backup(parent: nil, backup_id: nil, source_backup: nil, expire_time: nil, encryption_config: nil) -> ::Gapic::Operation

Starts copying a Cloud Spanner Backup. The returned backup long-running operation will have a name of the format projects/<project>/instances/<instance>/backups/<backup>/operations/<operation_id> and can be used to track copying of the backup. The operation is associated with the destination backup. The metadata field type is CopyBackupMetadata. The response field type is Backup, if successful. Cancelling the returned operation will stop the copying and delete the destination backup. Concurrent CopyBackup requests can run on the same source backup.

Overloads 
def copy_backup(request, options = nil) -> ::Gapic::Operation
Pass arguments to copy_backup via a request object, either of type CopyBackupRequest or an equivalent Hash.
Parameters
  • request (::Google::Cloud::Spanner::Admin::Database::V1::CopyBackupRequest, ::Hash) — A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.
  • options (::Gapic::CallOptions, ::Hash) — Overrides the default settings for this call, e.g, timeout, retries etc. Optional. 
def copy_backup(parent: nil, backup_id: nil, source_backup: nil, expire_time: nil, encryption_config: nil) -> ::Gapic::Operation
Pass arguments to copy_backup via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).
Parameters
  • parent (::String) — Required. The name of the destination instance that will contain the backup copy. Values are of the form: projects/<project>/instances/<instance>.
  • backup_id (::String) — Required. The id of the backup copy. The backup_id appended to parent forms the full backup_uri of the form projects/<project>/instances/<instance>/backups/<backup>.
  • source_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/<project>/instances/<instance>/backups/<backup>.
  • expire_time (::Google::Protobuf::Timestamp, ::Hash) — 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.
  • encryption_config (::Google::Cloud::Spanner::Admin::Database::V1::CopyBackupEncryptionConfig, ::Hash) — 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.
Yields
  • (result, operation) — Access the result along with the TransportOperation object
Yield Parameters
  • result (::Gapic::Operation)
  • operation (::Gapic::Rest::TransportOperation)
Returns
  • (::Gapic::Operation)
Raises
  • (::Google::Cloud::Error) — if the REST call is aborted.

#list_backup_operations

def list_backup_operations(request, options = nil) -> ::Gapic::Operation
def list_backup_operations(parent: nil, filter: nil, page_size: nil, page_token: nil) -> ::Gapic::Operation

Lists the backup long-running operations in the given instance. A backup operation has a name of the form projects/<project>/instances/<instance>/backups/<backup>/operations/<operation>. The long-running operation metadata field type metadata.type_url describes the type of the metadata. Operations returned include those that have completed/failed/canceled within the last 7 days, and pending operations. Operations returned are ordered by operation.metadata.value.progress.start_time in descending order starting from the most recently started operation.

Overloads 
def list_backup_operations(request, options = nil) -> ::Gapic::Operation
Pass arguments to list_backup_operations via a request object, either of type ListBackupOperationsRequest or an equivalent Hash.
Parameters
  • request (::Google::Cloud::Spanner::Admin::Database::V1::ListBackupOperationsRequest, ::Hash) — A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.
  • options (::Gapic::CallOptions, ::Hash) — Overrides the default settings for this call, e.g, timeout, retries etc. Optional. 
def list_backup_operations(parent: nil, filter: nil, page_size: nil, page_token: nil) -> ::Gapic::Operation
Pass arguments to list_backup_operations via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).
Parameters
  • parent (::String) — Required. The instance of the backup operations. Values are of the form projects/<project>/instances/<instance>.
  • filter (::String) —

    An expression that filters the list of returned backup operations.

    A filter expression consists of a field name, a comparison operator, and a value for filtering. The value must be a string, a number, or a boolean. The comparison operator must be one of: <, >, <=, >=, !=, =, or :. Colon : is the contains operator. Filter rules are not case sensitive.

    The following fields in the operation are eligible for filtering:

    • name - The name of the long-running operation
    • done - False if the operation is in progress, else true.
    • metadata.@type - the type of metadata. For example, the type string for CreateBackupMetadata is type.googleapis.com/google.spanner.admin.database.v1.CreateBackupMetadata.
    • metadata.<field_name> - any field in metadata.value. metadata.@type must be specified first if filtering on metadata fields.
    • error - Error associated with the long-running operation.
    • response.@type - the type of response.
    • response.<field_name> - any field in response.value.

    You can combine multiple expressions by enclosing each expression in parentheses. By default, expressions are combined with AND logic, but you can specify AND, OR, and NOT logic explicitly.

    Here are a few examples:

    • done:true - The operation is complete.
    • (metadata.@type=type.googleapis.com/google.spanner.admin.database.v1.CreateBackupMetadata) AND \ metadata.database:prod - Returns operations where:
      • The operation's metadata type is CreateBackupMetadata.
      • The source database name of backup contains the string "prod".
    • (metadata.@type=type.googleapis.com/google.spanner.admin.database.v1.CreateBackupMetadata) AND \ (metadata.name:howl) AND \ (metadata.progress.start_time < \"2018-03-28T14:50:00Z\") AND \ (error:*) - Returns operations where:
      • The operation's metadata type is CreateBackupMetadata.
      • The backup name contains the string "howl".
      • The operation started before 2018-03-28T14:50:00Z.
      • The operation resulted in an error.
    • (metadata.@type=type.googleapis.com/google.spanner.admin.database.v1.CopyBackupMetadata) AND \ (metadata.source_backup:test) AND \ (metadata.progress.start_time < \"2022-01-18T14:50:00Z\") AND \ (error:*) - Returns operations where:
      • The operation's metadata type is CopyBackupMetadata.
      • The source backup name contains the string "test".
      • The operation started before 2022-01-18T14:50:00Z.
      • The operation resulted in an error.
    • ((metadata.@type=type.googleapis.com/google.spanner.admin.database.v1.CreateBackupMetadata) AND \ (metadata.database:test_db)) OR \ ((metadata.@type=type.googleapis.com/google.spanner.admin.database.v1.CopyBackupMetadata) AND \ (metadata.source_backup:test_bkp)) AND \ (error:*) - Returns operations where:
      • The operation's metadata matches either of criteria:
        • The operation's metadata type is CreateBackupMetadata AND the source database name of the backup contains the string "test_db"
        • The operation's metadata type is CopyBackupMetadata AND the source backup name contains the string "test_bkp"
      • The operation resulted in an error.
  • page_size (::Integer) — Number of operations to be returned in the response. If 0 or less, defaults to the server's maximum allowed page size.
  • page_token (::String) — If non-empty, page_token should contain a next_page_token from a previous ListBackupOperationsResponse to the same parent and with the same filter.
Yields
  • (result, operation) — Access the result along with the TransportOperation object
Yield Parameters
  • result (::Gapic::Operation)
  • operation (::Gapic::Rest::TransportOperation)
Returns
  • (::Gapic::Operation)
Raises
  • (::Google::Cloud::Error) — if the REST call is aborted.

#restore_database

def restore_database(request, options = nil) -> ::Gapic::Operation
def restore_database(parent: nil, database_id: nil, backup: nil, encryption_config: nil) -> ::Gapic::Operation

Create a new database by restoring from a completed backup. The new database must be in the same project and in an instance with the same instance configuration as the instance containing the backup. The returned database [long-running operation][google.longrunning.Operation] has a name of the format projects/<project>/instances/<instance>/databases/<database>/operations/<operation_id>, and can be used to track the progress of the operation, and to cancel it. The metadata field type is RestoreDatabaseMetadata. The response type is Database, if successful. Cancelling the returned operation will stop the restore and delete the database. There can be only one database being restored into an instance at a time. Once the restore operation completes, a new restore operation can be initiated, without waiting for the optimize operation associated with the first restore to complete.

Overloads 
def restore_database(request, options = nil) -> ::Gapic::Operation

  • parent (::String) — Required. The name of the instance in which to create the restored database. This instance must be in the same project and have the same instance configuration as the instance containing the source backup. Values are of the form projects/<project>/instances/<instance>.
  • database_id (::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/<project>/instances/<instance>/databases/<database_id>.
  • backup (::String) — Name of the backup from which to restore. Values are of the form projects/<project>/instances/<instance>/backups/<backup>.
  • encryption_config (::Google::Cloud::Spanner::Admin::Database::V1::RestoreDatabaseEncryptionConfig, ::Hash) — 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.
Yields

#update_database

def update_database(request, options = nil) -> ::Gapic::Operation
def update_database(database: nil, update_mask: nil) -> ::Gapic::Operation

Updates a Cloud Spanner database. The returned long-running operation can be used to track the progress of updating the database. If the named database does not exist, returns NOT_FOUND.

While the operation is pending:

  • The database's reconciling field is set to true.
  • Cancelling the operation is best-effort. If the cancellation succeeds, the operation metadata's cancel_time is set, the updates are reverted, and the operation terminates with a CANCELLED status.
  • New UpdateDatabase requests will return a FAILED_PRECONDITION error until the pending operation is done (returns successfully or with error).
  • Reading the database via the API continues to give the pre-request values.

Upon completion of the returned operation:

  • The new values are in effect and readable via the API.
  • The database's reconciling field becomes false.

The returned long-running operation will have a name of the format projects/<project>/instances/<instance>/databases/<database>/operations/<operation_id> and can be used to track the database modification. The metadata field type is UpdateDatabaseMetadata. The response field type is Database, if successful.

Overloads 
def update_database(request, options = nil) -> ::Gapic::Operation
Pass arguments to update_database via a request object, either of type UpdateDatabaseRequest or an equivalent Hash.
Parameters
  • request (::Google::Cloud::Spanner::Admin::Database::V1::UpdateDatabaseRequest, ::Hash) — A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.
  • options (::Gapic::CallOptions, ::Hash) — Overrides the default settings for this call, e.g, timeout, retries etc. Optional. 
def update_database(database: nil, update_mask: nil) -> ::Gapic::Operation
Pass arguments to update_database via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

#update_database_ddl

def update_database_ddl(request, options = nil) -> ::Gapic::Operation
def update_database_ddl(database: nil, statements: nil, operation_id: nil, proto_descriptors: nil) -> ::Gapic::Operation

Updates the schema of a Cloud Spanner database by creating/altering/dropping tables, columns, indexes, etc. The returned long-running operation will have a name of the format <database_name>/operations/<operation_id> and can be used to track execution of the schema change(s). The metadata field type is UpdateDatabaseDdlMetadata. The operation has no response.

Overloads 
def update_database_ddl(request, options = nil) -> ::Gapic::Operation
Pass arguments to update_database_ddl via a request object, either of type UpdateDatabaseDdlRequest or an equivalent Hash.
Parameters
  • request (::Google::Cloud::Spanner::Admin::Database::V1::UpdateDatabaseDdlRequest, ::Hash) — A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.
  • options (::Gapic::CallOptions, ::Hash) — Overrides the default settings for this call, e.g, timeout, retries etc. Optional. 
def update_database_ddl(database: nil, statements: nil, operation_id: nil, proto_descriptors: nil) -> ::Gapic::Operation
Pass arguments to update_database_ddl via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).
Parameters
  • database (::String) — Required. The database to update.
  • statements (::Array<::String>) — Required. DDL statements to be applied to the database.
  • operation_id (::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: <database>/operations/<operation_id>.

    operation_id should be unique within the database, and must be a valid identifier: [a-z][a-z0-9_]*. Note that automatically-generated operation IDs always begin with an underscore. If the named operation already exists, UpdateDatabaseDdl returns ALREADY_EXISTS.

  • proto_descriptors (::String) — 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.
Yields
  • (result, operation) — Access the result along with the TransportOperation object
Yield Parameters
  • result (::Gapic::Operation)
  • operation (::Gapic::Rest::TransportOperation)
Returns
  • (::Gapic::Operation)
Raises
  • (::Google::Cloud::Error) — if the REST call is aborted.
