Generally Available: Cascading read replicas in Azure Database for PostgreSQL

Cascading read replicas are now generally available in Azure Database for PostgreSQL, giving you greater flexibility to scale read‑intensive workloads. You can now create read replicas from existing ones, creating up to 30 across two levels of replication. Each source supports up to five read replicas. This capability enables you to design advanced, multi‑level replication topologies tailored for globally distributed applications. By placing replicas closer to your users, you can improve read response times, efficiently distribute read traffic, and reduce read pressure on the primary server.
