Method: googleapis.sqladmin.v1beta4.instances.failover

Initiates a manual failover of a high availability (HA) primary instance to a standby instance, which becomes the primary instance. Users are then rerouted to the new primary. For more information, see the Overview of high availability page in the Cloud SQL documentation. If using Legacy HA (MySQL only), this causes the instance to failover to its failover replica instance.

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. See the Connectors reference.

The connector uses polling to monitor the long-running operation, which might generate additional billable steps. For more information about retries and long-running operations, refer to Understand connectors.

The polling policy for the long-running operation can be configured. To set the connector-specific parameters (connector_params), refer to Invoke a connector call.

Raised exceptions

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.
