EDB Postgres Distributed 5.2.0 release notes v5
Released: 04 Aug 2023
EDB Postgres Distributed version 5.2.0 is a minor version of EDB Postgres Distributed.
Highlights of EDB Postgres Distributed 5.2
- Parallel Apply is now available for PGD’s Commit at Most Once (CAMO) synchronous commit scope and improving replication performance.
- Parallel Apply for native Postgres asynchronous and synchronous replication has been improved for workloads where the same key is being modified concurrently by multiple transactions to maintain commit sequence and avoid deadlocks.
- PGD Proxy has added HTTP(S) APIs to allow the health of the proxy to be monitored directly for readiness and liveness. See Proxy health check.
Recommended upgrade
We recommend that users of PGD 5.1 upgrade to PGD 5.2.
