// Initiates the failover process for a Neptune global database. A failover for a
// Neptune 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 secondary DB cluster are switched. The selected
// secondary DB cluster assumes full read/write capabilities for the Neptune global
// database. This action applies only to Neptune global databases. This action is
// only intended for use on healthy Neptune global databases with healthy Neptune
// DB clusters and no region-wide outages, to test disaster recovery scenarios or
// to reconfigure the global database topology.
