FailoverDBCluster (updated) Link ¶
Changes (request)
{'TargetDBInstanceIdentifier': 'string'}

Forces a failover for a DB cluster.

A failover for a DB cluster promotes one of the read-only instances in the DB cluster to the master DB instance (the cluster writer) and deletes the current primary instance.

Amazon Aurora will automatically fail over to a read-only instance, if one exists, when the primary instance fails. You can force a failover when you want to simulate a failure of a DB instance for testing. Because each instance in a DB cluster has its own endpoint address, you will need to clean up and re-establish any existing connections that use those endpoint addresses when the failover is complete.

For more information on Amazon Aurora, see Aurora on Amazon RDS in the Amazon RDS User Guide.

Request Syntax

client.failover_db_cluster(
    DBClusterIdentifier='string',
    TargetDBInstanceIdentifier='string'
)
type DBClusterIdentifier

string

param DBClusterIdentifier

A DB cluster identifier to force a failover for. This parameter is not case-sensitive.

Constraints:

  • Must contain from 1 to 63 alphanumeric characters or hyphens

  • First character must be a letter

  • Cannot end with a hyphen or contain two consecutive hyphens

type TargetDBInstanceIdentifier

string

param TargetDBInstanceIdentifier

The name of the instance to promote to the primary instance.

You must specify the instance identifier for an Aurora Replica in the DB cluster. For example, mydbcluster-replica1 .
