Method: googleapis.spanner.v1.projects.instances.databases.restore

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//instances//databases//operations/, 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.

This method waits—the workflow execution is paused—until the operation is complete, fails, or times out. The default timeout value is 1800 seconds (30 minutes) and can be changed to a maximum value of 31536000 seconds (one year) for long-running operations using the connector_params field.

The connector uses polling to monitor the long-running operation, which might generate additional billable steps. The polling policy for the long-running operation can be configured. For example, if you set skip_polling to True, the connector invocation call is non-blocking if the initial request succeeds; otherwise, retries might occur.

For more information about connector-specific parameters (connector_params), see Invoke a connector call.

Arguments

Parameters
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//instances/.
body

object (RestoreDatabaseRequest)

Required.

Raised exceptions

Exceptions
ConnectionError In case of a network problem (such as DNS failure or refused connection).
HttpError If the response status is >= 400 (excluding 429 and 503).
TimeoutError If a long-running operation takes longer to finish than the specified timeout limit.
TypeError If an operation or function receives an argument of the wrong type.
ValueError If an operation or function receives an argument of the right type but an inappropriate value. For example, a negative timeout.
OperationError If the long-running operation finished unsuccessfully.
ResponseTypeError If the long-running operation returned a response of the wrong type.

Response

If successful, the response contains an instance of Operation.
