Cloud Spanner V1 Client - Class DatabaseAdminClient (1.61.0)

Reference documentation and code samples for the Cloud Spanner V1 Client class DatabaseAdminClient.

Service Description: Cloud Spanner Database Admin API

The Cloud Spanner Database Admin API can be used to:

create, drop, and list databases
update the schema of pre-existing databases
create, delete and list backups for a database
restore a database from an existing backup

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:

$databaseAdminClient = new DatabaseAdminClient();
try {
    $formattedParent = $databaseAdminClient->instanceName('[PROJECT]', '[INSTANCE]');
    $backupId = 'backup_id';
    $formattedSourceBackup = $databaseAdminClient->backupName('[PROJECT]', '[INSTANCE]', '[BACKUP]');
    $expireTime = new Timestamp();
    $operationResponse = $databaseAdminClient->copyBackup($formattedParent, $backupId, $formattedSourceBackup, $expireTime);
    $operationResponse->pollUntilComplete();
    if ($operationResponse->operationSucceeded()) {
        $result = $operationResponse->getResult();
        // doSomethingWith($result)
    } else {
        $error = $operationResponse->getError();
        // handleError($error)
    }
    // Alternatively:
    // start the operation, keep the operation name, and resume later
    $operationResponse = $databaseAdminClient->copyBackup($formattedParent, $backupId, $formattedSourceBackup, $expireTime);
    $operationName = $operationResponse->getName();
    // ... do other work
    $newOperationResponse = $databaseAdminClient->resumeOperation($operationName, 'copyBackup');
    while (!$newOperationResponse->isDone()) {
        // ... do other work
        $newOperationResponse->reload();
    }
    if ($newOperationResponse->operationSucceeded()) {
        $result = $newOperationResponse->getResult();
        // doSomethingWith($result)
    } else {
        $error = $newOperationResponse->getError();
        // handleError($error)
    }
} finally {
    $databaseAdminClient->close();
}

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parseName method to extract the individual identifiers contained within formatted names that are returned by the API.

Namespace

Google \ Cloud \ Spanner \ Admin \ Database \ V1

Methods

__construct

Constructor.

Parameters
Name	Description
`options`	`array` Optional. Options for configuring the service API wrapper.
`↳ apiEndpoint`	`string` The address of the API remote host. May optionally include the port, formatted as "
`↳ credentials`	`string\|array\|FetchAuthTokenInterface\|CredentialsWrapper` The credentials to be used by the client to authorize API calls. This option accepts either a path to a credentials file, or a decoded credentials file as a PHP array. Advanced usage: In addition, this option can also accept a pre-constructed Google\Auth\FetchAuthTokenInterface object or Google\ApiCore\CredentialsWrapper object. Note that when one of these objects are provided, any settings in $credentialsConfig will be ignored.
`↳ credentialsConfig`	`array` Options used to configure credentials, including auth token caching, for the client. For a full list of supporting configuration options, see Google\ApiCore\CredentialsWrapper::build() .
`↳ disableRetries`	`bool` Determines whether or not retries defined by the client configuration should be disabled. Defaults to `false`.
`↳ clientConfig`	`string\|array` Client method configuration, including retry settings. This option can be either a path to a JSON file, or a PHP array containing the decoded JSON data. By default this settings points to the default client config file, which is provided in the resources folder.
`↳ transport`	`string\|TransportInterface` The transport used for executing network requests. May be either the string `rest` or `grpc`. Defaults to `grpc` if gRPC support is detected on the system. Advanced usage: Additionally, it is possible to pass in an already instantiated Google\ApiCore\Transport\TransportInterface object. Note that when this object is provided, any settings in $transportConfig, and any $apiEndpoint setting, will be ignored.
`↳ transportConfig`	`array` Configuration options that will be used to construct the transport. Options for each supported transport type should be passed in a key for that transport. For example: $transportConfig = [ 'grpc' => [...], 'rest' => [...], ]; See the Google\ApiCore\Transport\GrpcTransport::build() and Google\ApiCore\Transport\RestTransport::build() methods for the supported options.
`↳ clientCertSource`	`callable` A callable which returns the client cert as a string. This can be used to provide a certificate and private key to the transport layer for mTLS.

copyBackup

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 backup. Concurrent CopyBackup requests can run on the same source backup.

Sample code:

$databaseAdminClient = new DatabaseAdminClient();
try {
    $formattedParent = $databaseAdminClient->instanceName('[PROJECT]', '[INSTANCE]');
    $backupId = 'backup_id';
    $formattedSourceBackup = $databaseAdminClient->backupName('[PROJECT]', '[INSTANCE]', '[BACKUP]');
    $expireTime = new Timestamp();
    $operationResponse = $databaseAdminClient->copyBackup($formattedParent, $backupId, $formattedSourceBackup, $expireTime);
    $operationResponse->pollUntilComplete();
    if ($operationResponse->operationSucceeded()) {
        $result = $operationResponse->getResult();
        // doSomethingWith($result)
    } else {
        $error = $operationResponse->getError();
        // handleError($error)
    }
    // Alternatively:
    // start the operation, keep the operation name, and resume later
    $operationResponse = $databaseAdminClient->copyBackup($formattedParent, $backupId, $formattedSourceBackup, $expireTime);
    $operationName = $operationResponse->getName();
    // ... do other work
    $newOperationResponse = $databaseAdminClient->resumeOperation($operationName, 'copyBackup');
    while (!$newOperationResponse->isDone()) {
        // ... do other work
        $newOperationResponse->reload();
    }
    if ($newOperationResponse->operationSucceeded()) {
        $result = $newOperationResponse->getResult();
        // doSomethingWith($result)
    } else {
        $error = $newOperationResponse->getError();
        // handleError($error)
    }
} finally {
    $databaseAdminClient->close();
}

Parameters
Name	Description
`parent`	`string` Required. The name of the destination instance that will contain the backup copy. Values are of the form: `projects/<project>/instances/<instance>`.
`backupId`	`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>`.
`sourceBackup`	`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>`.
`expireTime`	`Google\Protobuf\Timestamp` 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.
`optionalArgs`	`array` Optional.
`↳ encryptionConfig`	`CopyBackupEncryptionConfig` 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`.

Parameters
Name	Description
`parent`	`string` Required. The instance of the backup operations. Values are of the form `projects/<project>/instances/<instance>`.
`optionalArgs`	`array` Optional.
`↳ 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 database the backup was taken from has a name containing 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 of the copied 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 database the backup was taken from has name containing string "test_db" * The operation's metadata type is CopyBackupMetadata AND the backup the backup was copied from has name containing string "test_bkp" * The operation resulted in an error.
`↳ pageSize`	`int` The maximum number of resources contained in the underlying API response. The API may return fewer values in a page, even if there are additional values to be retrieved.
`↳ pageToken`	`string` A page token is used to specify a page of values to be returned. If no page token is specified (the default), the first page of values will be returned. Any page token used here must have been generated by a previous call to the API.
`↳ retrySettings`	`RetrySettings\|array` Retry settings to use for this call. Can be a Google\ApiCore\RetrySettings object, or an associative array of retry settings parameters. See the documentation on Google\ApiCore\RetrySettings for example usage.

Returns

A database operation has a name of the form projects/<project>/instances/<instance>/databases/<database>/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.

Sample code:

$databaseAdminClient = new DatabaseAdminClient();
try {
    $formattedParent = $databaseAdminClient->instanceName('[PROJECT]', '[INSTANCE]');
    // Iterate over pages of elements
    $pagedResponse = $databaseAdminClient->listDatabaseOperations($formattedParent);
    foreach ($pagedResponse->iteratePages() as $page) {
        foreach ($page as $element) {
            // doSomethingWith($element);
        }
    }
    // Alternatively:
    // Iterate through all elements
    $pagedResponse = $databaseAdminClient->listDatabaseOperations($formattedParent);
    foreach ($pagedResponse->iterateAllElements() as $element) {
        // doSomethingWith($element);
    }
} finally {
    $databaseAdminClient->close();
}

Parameters
Name	Description
`parent`	`string` Required. The instance of the database operations. Values are of the form `projects/<project>/instances/<instance>`.
`optionalArgs`	`array` Optional.
`↳ filter`	`string` An expression that filters the list of returned 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 RestoreDatabaseMetadata is `type.googleapis.com/google.spanner.admin.database.v1.RestoreDatabaseMetadata`. * `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. However, 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.RestoreDatabaseMetadata) AND` \ `(metadata.source_type:BACKUP) AND` \ `(metadata.backup_info.backup:backup_howl) AND` \ `(metadata.name:restored_howl) AND` \ `(metadata.progress.start_time < \"2018-03-28T14:50:00Z\") AND` \ `(error:)` - Return operations where: The operation's metadata type is RestoreDatabaseMetadata. * The database is restored from a backup. * The backup name contains "backup_howl". * The restored database's name contains "restored_howl". * The operation started before 2018-03-28T14:50:00Z. * The operation resulted in an error.
`↳ pageSize`	`int` The maximum number of resources contained in the underlying API response. The API may return fewer values in a page, even if there are additional values to be retrieved.
`↳ pageToken`	`string` A page token is used to specify a page of values to be returned. If no page token is specified (the default), the first page of values will be returned. Any page token used here must have been generated by a previous call to the API.
`↳ retrySettings`	`RetrySettings\|array` Retry settings to use for this call. Can be a Google\ApiCore\RetrySettings object, or an associative array of retry settings parameters. See the documentation on Google\ApiCore\RetrySettings for example usage.

Returns

restoreDatabase

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 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.

Sample code:

$databaseAdminClient = new DatabaseAdminClient();
try {
    $formattedParent = $databaseAdminClient->instanceName('[PROJECT]', '[INSTANCE]');
    $databaseId = 'database_id';
    $operationResponse = $databaseAdminClient->restoreDatabase($formattedParent, $databaseId);
    $operationResponse->pollUntilComplete();
    if ($operationResponse->operationSucceeded()) {
        $result = $operationResponse->getResult();
        // doSomethingWith($result)
    } else {
        $error = $operationResponse->getError();
        // handleError($error)
    }
    // Alternatively:
    // start the operation, keep the operation name, and resume later
    $operationResponse = $databaseAdminClient->restoreDatabase($formattedParent, $databaseId);
    $operationName = $operationResponse->getName();
    // ... do other work
    $newOperationResponse = $databaseAdminClient->resumeOperation($operationName, 'restoreDatabase');
    while (!$newOperationResponse->isDone()) {
        // ... do other work
        $newOperationResponse->reload();
    }
    if ($newOperationResponse->operationSucceeded()) {
        $result = $newOperationResponse->getResult();
        // doSomethingWith($result)
    } else {
        $error = $newOperationResponse->getError();
        // handleError($error)
    }
} finally {
    $databaseAdminClient->close();
}

Parameters

setIamPolicy

Sets the access control policy on a database or backup resource.

Replaces any existing policy.

Authorization requires spanner.databases.setIamPolicy permission on resource. For backups, authorization requires spanner.backups.setIamPolicy permission on resource.

Sample code:

$databaseAdminClient = new DatabaseAdminClient();
try {
    $resource = 'resource';
    $policy = new Policy();
    $response = $databaseAdminClient->setIamPolicy($resource, $policy);
} finally {
    $databaseAdminClient->close();
}

Parameters
Name	Description
`resource`	`string` REQUIRED: The resource for which the policy is being specified. See the operation documentation for the appropriate value for this field.
`policy`	`Google\Cloud\Iam\V1\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 Cloud Platform services (such as Projects) might reject them.
`optionalArgs`	`array` Optional.
`↳ updateMask`	`FieldMask` OPTIONAL: A FieldMask specifying which fields of the policy to modify. Only the fields in the mask will be modified. If no mask is provided, the following default mask is used: `paths: "bindings, etag"`
`↳ retrySettings`	`RetrySettings\|array` Retry settings to use for this call. Can be a Google\ApiCore\RetrySettings object, or an associative array of retry settings parameters. See the documentation on Google\ApiCore\RetrySettings for example usage.

Returns
Type	Description

testIamPermissions

Returns permissions that the caller has on the specified database or backup resource.

Attempting this RPC on a non-existent Cloud Spanner database will result in a NOT_FOUND error if the user has spanner.databases.list permission on the containing Cloud Spanner instance. Otherwise returns an empty set of permissions. Calling this method on a backup that does not exist will result in a NOT_FOUND error if the user has spanner.backups.list permission on the containing instance.

Sample code:

$databaseAdminClient = new DatabaseAdminClient();
try {
    $resource = 'resource';
    $permissions = [];
    $response = $databaseAdminClient->testIamPermissions($resource, $permissions);
} finally {
    $databaseAdminClient->close();
}

Parameters
Name	Description
`resource`	`string` REQUIRED: The resource for which the policy detail is being requested. See the operation documentation for the appropriate value for this field.
`permissions`	`string[]` The set of permissions to check for the `resource`. Permissions with wildcards (such as '' or 'storage.') are not allowed. For more information see IAM Overview.
`optionalArgs`	`array` Optional.
`↳ retrySettings`	`RetrySettings\|array` Retry settings to use for this call. Can be a Google\ApiCore\RetrySettings object, or an associative array of retry settings parameters. See the documentation on Google\ApiCore\RetrySettings for example usage.

Returns

Updates a pending or completed Backup.

Sample code:

$databaseAdminClient = new DatabaseAdminClient();
try {
    $backup = new Backup();
    $updateMask = new FieldMask();
    $response = $databaseAdminClient->updateBackup($backup, $updateMask);
} finally {

Name	Description
`backup`	`Google\Cloud\Spanner\Admin\Database\V1\Backup` Required. The backup to update. `backup.name`, and the fields to be updated as specified by `update_mask` are required. Other fields are ignored. Update is only supported for the following fields: `backup.expire_time`.
`updateMask`	`Google\Protobuf\FieldMask` Required. A mask specifying which fields (e.g. `expire_time`) in the Backup resource should be updated. This mask is relative to the Backup resource, not to the request message. The field mask must always be specified; this prevents any future fields from being erased accidentally by clients that do not know about them.
`optionalArgs`	`array` Optional.
`↳ retrySettings`	`RetrySettings\|array` Retry settings to use for this call. Can be a Google\ApiCore\RetrySettings object, or an associative array of retry settings parameters. See the documentation on Google\ApiCore\RetrySettings for example usage.

updateDatabase

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.

Sample code:

$databaseAdminClient = new DatabaseAdminClient();
try {
    $database = new Database();
    $updateMask = new FieldMask();
    $operationResponse = $databaseAdminClient->updateDatabase($database, $updateMask);
    $operationResponse->pollUntilComplete();
    if ($operationResponse->operationSucceeded()) {
        $result = $operationResponse->getResult();
        // doSomethingWith($result)
    } else {
        $error = $operationResponse->getError();
        // handleError($error)
    }
    // Alternatively:
    // start the operation, keep the operation name, and resume later
    $operationResponse = $databaseAdminClient->updateDatabase($database, $updateMask);
    $operationName = $operationResponse->getName();
    // ... do other work
    $newOperationResponse = $databaseAdminClient->resumeOperation($operationName, 'updateDatabase');
    while (!$newOperationResponse->isDone()) {
        // ... do other work
        $newOperationResponse->reload();
    }
    if ($newOperationResponse->operationSucceeded()) {
        $result = $newOperationResponse->getResult();
        // doSomethingWith($result)
    } else {
        $error = $newOperationResponse->getError();
        // handleError($error)
    }
} finally {
    $databaseAdminClient->close();
}

Parameters
Name	Description
`database`	`Google\Cloud\Spanner\Admin\Database\V1\Database` Required. The database to update. The `name` field of the database is of the form `projects/<project>/instances/<instance>/databases/<database>`.
`updateMask`	`Google\Protobuf\FieldMask` Required. The list of fields to update. Currently, only `enable_drop_protection` field can be updated.
`optionalArgs`	`array` Optional.
`↳ retrySettings`	`RetrySettings\|array` Retry settings to use for this call. Can be a Google\ApiCore\RetrySettings object, or an associative array of retry settings parameters. See the documentation on Google\ApiCore\RetrySettings for example usage.

Returns
Type	Description
`Google\ApiCore\OperationResponse`

updateDatabaseDdl

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.

Sample code:

$databaseAdminClient = new DatabaseAdminClient();
try {
    $formattedDatabase = $databaseAdminClient->databaseName('[PROJECT]', '[INSTANCE]', '[DATABASE]');
    $statements = [];
    $operationResponse = $databaseAdminClient->updateDatabaseDdl($formattedDatabase, $statements);
    $operationResponse->pollUntilComplete();
    if ($operationResponse->operationSucceeded()) {
        // operation succeeded and returns no value
    } else {
        $error = $operationResponse->getError();
        // handleError($error)
    }
    // Alternatively:
    // start the operation, keep the operation name, and resume later
    $operationResponse = $databaseAdminClient->updateDatabaseDdl($formattedDatabase, $statements);
    $operationName = $operationResponse->getName();
    // ... do other work
    $newOperationResponse = $databaseAdminClient->resumeOperation($operationName, 'updateDatabaseDdl');
    while (!$newOperationResponse->isDone()) {
        // ... do other work
        $newOperationResponse->reload();
    }
    if ($newOperationResponse->operationSucceeded()) {
        // operation succeeded and returns no value
    } else {
        $error = $newOperationResponse->getError();
        // handleError($error)
    }
} finally {
    $databaseAdminClient->close();
}

Parameters
Name	Description
`database`	`string` Required. The database to update.
`statements`	`string[]` Required. DDL statements to be applied to the database.
`optionalArgs`	`array` Optional.
`↳ operationId`	`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`.
`↳ retrySettings`	`RetrySettings\|array` Retry settings to use for this call. Can be a Google\ApiCore\RetrySettings object, or an associative array of retry settings parameters. See the documentation on Google\ApiCore\RetrySettings for example usage.
