Learn about Citus on Microsoft Azure in our latest post about use cases: When to use Hyperscale (Citus) to scale out Postgres.
As part of the Citus team (Citus scales out Postgres horizontally, but that’s not all we work on), I’ve been working on pg_auto_failover for quite some time now and I’m excited that we have now introduced pg_auto_failover as Open Source, to give you automated failover and high availability!
pg_auto_failover, our goal was this: to provide an easy to set up Business Continuity solution for Postgres that implements fault tolerance of any one node in the system. The documentation chapter about the pg_auto_failover architecture includes the following:
It is important to understand that pg_auto_failover is optimized for Business Continuity. In the event of losing a single node, then pg_auto_failover is capable of continuing the PostgreSQL service, and prevents any data loss when doing so, thanks to PostgreSQL Synchronous Replication.
Introduction to pg_auto_failover
The pg_auto_failover solution for Postgres is meant to provide an easy to setup and reliable automated failover solution. This solution includes software driven decision making for when to implement failover in production.Keep reading
