Patroni
Introduction
Patroni is a template for you to create your own customized, high-availability solution using Python and - for maximum accessibility - a distributed configuration store like ZooKeeper, etcd, Consul or Kubernetes. Database engineers, DBAs, DevOps engineers, and SREs who are looking to quickly deploy HA PostgreSQL in the datacenter-or anywhere else-will hopefully find it useful.
We call Patroni a "template" because it is far from being a one-size-fits-all or plug-and-play replication system. It will have its own caveats. Use wisely. There are many ways to run high availability with PostgreSQL; for a list, see the PostgreSQL Documentation.
Currently supported PostgreSQL versions: 9.3 to 15.
Note to Citus users: Starting from 3.0 Patroni nicely integrates with
the Citus database extension to
Postgres. Please check the Citus support page <citus> in the Patroni
documentation for more info about how to use Patroni high availability
together with a Citus distributed cluster.
Note to Kubernetes users: Patroni can run natively on top of
Kubernetes. Take a look at the Kubernetes <kubernetes> chapter of
the Patroni documentation.
