Failover Db Cluster

docdb_failover_db_cluster

R Documentation

Forces a failover for a cluster

Description

Forces a failover for a cluster.

A failover for a cluster promotes one of the Amazon DocumentDB replicas (read-only instances) in the cluster to be the primary instance (the cluster writer).

If the primary instance fails, Amazon DocumentDB automatically fails over to an Amazon DocumentDB replica, if one exists. You can force a failover when you want to simulate a failure of a primary instance for testing.

Usage

docdb_failover_db_cluster(DBClusterIdentifier,
  TargetDBInstanceIdentifier)

Arguments

DBClusterIdentifier

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

Constraints:

• Must match the identifier of an existing DBCluster.

TargetDBInstanceIdentifier

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

You must specify the instance identifier for an Amazon DocumentDB replica in the cluster. For example, mydbcluster-replica1.
