Class DatabaseAdminClient (3.50.1)

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, copy and list backups for a database
• restore a database from an existing backup

Return the API endpoint used by the client instance.

Returns the transport used by the client instance.

Return the universe domain used by the client instance.

Instantiates the database admin client.

Releases underlying transport's resources.

Returns a fully-qualified backup string.

Returns a fully-qualified backup_schedule string.

Starts asynchronous cancellation on a long-running operation.

The server makes a best effort to cancel the operation, but success is not guaranteed. If the server doesn't support this method, it returns google.rpc.Code.UNIMPLEMENTED.

Returns a fully-qualified billing_account string.

Returns a fully-qualified folder string.

Returns a fully-qualified location string.

Returns a fully-qualified organization string.

Returns a fully-qualified project string.

Starts copying a Cloud Spanner Backup. The returned backup long-running operation][google.longrunning.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][google.longrunning.Operation.metadata] field type is CopyBackupMetadata][google.spanner.admin.database.v1.CopyBackupMetadata]. The response][google.longrunning.Operation.response] field type is Backup][google.spanner.admin.database.v1.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.

Starts creating a new Cloud Spanner Backup. The returned backup long-running operation][google.longrunning.Operation] will have a name of the format projects/<project>/instances/<instance>/backups/<backup>/operations/<operation_id> and can be used to track creation of the backup. The metadata][google.longrunning.Operation.metadata] field type is CreateBackupMetadata][google.spanner.admin.database.v1.CreateBackupMetadata]. The response][google.longrunning.Operation.response] field type is Backup][google.spanner.admin.database.v1.Backup], if successful. Cancelling the returned operation will stop the creation and delete the backup. There can be only one pending backup creation per database. Backup creation of different databases can run concurrently.

The client cert source is determined in the following order: (1) if GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is not "true", the client cert source is None. (2) if client_options.client_cert_source is provided, use the provided one; if the default client cert source exists, use the default one; otherwise the client cert source is None.

The API endpoint is determined in the following order: (1) if client_options.api_endpoint if provided, use the provided one. (2) if GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is "always", use the default mTLS endpoint; if the environment variable is "never", use the default API endpoint; otherwise if client cert source exists, use the default mTLS endpoint, otherwise use the default API endpoint.

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.

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][google.longrunning.Operation.metadata] field type is RestoreDatabaseMetadata][google.spanner.admin.database.v1.RestoreDatabaseMetadata]. The response][google.longrunning.Operation.response] type is Database][google.spanner.admin.database.v1.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.

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

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.

Updates a Cloud Spanner database. The returned [long-running operation][google.longrunning.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][google.spanner.admin.database.v1.Database.reconciling] field is set to true.
• Cancelling the operation is best-effort. If the cancellation succeeds, the operation metadata's cancel_time][google.spanner.admin.database.v1.UpdateDatabaseMetadata.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][google.spanner.admin.database.v1.Database.reconciling] field becomes false.

The returned [long-running operation][google.longrunning.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][google.longrunning.Operation.metadata] field type is UpdateDatabaseMetadata][google.spanner.admin.database.v1.UpdateDatabaseMetadata]. The response][google.longrunning.Operation.response] field type is Database][google.spanner.admin.database.v1.Database], if successful.

Updates the schema of a Cloud Spanner database by creating/altering/dropping tables, columns, indexes, etc. The returned long-running operation][google.longrunning.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][google.longrunning.Operation.metadata] field type is UpdateDatabaseDdlMetadata][google.spanner.admin.database.v1.UpdateDatabaseDdlMetadata]. The operation has no response.
