// Initiates the failover process for an Aurora global database ( GlobalCluster ).
// A failover for an Aurora global database promotes one of secondary read-only DB
// clusters to be the primary DB cluster and demotes the primary DB cluster to
// being a secondary (read-only) DB cluster. In other words, the role of the
// current primary DB cluster and the selected (target) DB cluster are switched.
// The selected secondary DB cluster assumes full read/write capabilities for the
// Aurora global database. For more information about failing over an Amazon Aurora
// global database, see Managed planned failover for Amazon Aurora global databases (https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/aurora-global-database-disaster-recovery.html#aurora-global-database-disaster-recovery.managed-failover)
// in the Amazon Aurora User Guide. This action applies to GlobalCluster (Aurora
// global databases) only. Use this action only on healthy Aurora global databases
// with running Aurora DB clusters and no Region-wide outages, to test disaster
// recovery scenarios or to reconfigure your Aurora global database topology.
