Public preview: Read replicas for Azure Database for PostgreSQL Flexible Server
Published date: October 26, 2022
The read replica feature enables you to improve the performance and scale of read-intensive workloads. Read workloads can be isolated to the replicas, while write workloads can be directed to the primary. Read replicas can also be deployed in a different region and can be used as a read-write server in the event of a disaster recovery.
Replicas are updated asynchronously with the Postgres engine native physical replication technology. You can replicate from the primary server to up to five replicas.
