Hot standby enhances the AlloyDB high availability (HA) architecture to improve failover times and to ensure consistent performance after failover. AlloyDB continuously replicates transactions to the standby node to keep caches warm and to ensure that the node is ready to take over quickly during a failover. This feature is generally available (GA) in PostgreSQL 18 and is automatically enabled for all new instances. For more information, see the AlloyDB high availability overview.
