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

UpdateDatabase(UpdateDatabaseRequest, ServerCallContext)

public virtual Task<Operation> UpdateDatabase(UpdateDatabaseRequest request, ServerCallContext context)

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.
