failoverGlobalCluster

Promotes the specified secondary DB cluster to be the primary DB cluster in the global cluster when failing over a global cluster occurs.

Use this operation to respond to an unplanned event, such as a regional disaster in the primary region. Failing over can result in a loss of write transaction data that wasn't replicated to the chosen secondary before the failover event occurred. However, the recovery process that promotes a DB instance on the chosen seconday DB cluster to be the primary writer DB instance guarantees that the data is in a transactionally consistent state.
