Azure Database for PostgreSQL read replica preview

Posted on Thursday, February 7, 2019

Azure Database for PostgreSQL now supports asynchronous replication of data from one Azure Database for PostgreSQL server (the ‘master’) to up to five Azure Database for PostgreSQL servers (the ‘replicas’) in the same region. This allows read-heavy workloads to scale out and be balanced across replica servers according to your preferences. Replica servers are read-only; any writes are those replicated from data changes on the master. Stopping replication to a replica server causes it to become a standalone server that accepts reads and writes.
