AlloyDB for PostgreSQL Adds Write Endpoints, Cross-Region Failover, and OpenSearch Integration

AlloyDB write endpoints are now available in Preview . Write endpoints simplify database connection management by providing a stable domain name service (DNS) name for your applications, decoupling them from instance IP addresses. During disaster recovery switchovers or failovers, AlloyDB automatically updates the endpoint to point to the new primary instance. For more information, see Manage database connections with write endpoints .

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 .

External search with AlloyDB now supports OpenSearch in Preview . You can use the external_search_fdw extension to connect to an OpenSearch cluster and query its data directly from your database.
