Explanation
Managed planned failover. To relocate your primary database cluster to one of the secondary Regions in your Aurora global database, see Managed planned failovers with Amazon Aurora Global Database. With this feature, RPO is 0 (no data loss) and it synchronizes secondary DB clusters with the primary before making any other changes. RTO for this automated process is typically less than that of the manual failover.
