AlloyDB now supports cross-region failover in Preview.

AlloyDB now supports cross-region failover in Preview. You can optionally enable cross-region failover to automate the recreation of the original primary when a secondary cluster is promoted while maintaining your replication topology without requiring manual cluster deletion or re-creation. Cross-region failover is supported only for topologies with a single primary cluster and a single secondary cluster.

For more information, see About cross-region replication and Work with cross-region replication.
