Patroni 3.0: What's New and Future Plans
summary
Patroni 3.0 adds concrete behavior: a new distributed leader election and discovery protocol using external stores (Consul/etcd) with periodic updates and TTL, tighter handling of replication slots so replicas can keep slots across failover, and support for multiple synchronous replicas (sync standbys) with configurable wait policies. It improves connection handling (long TCP timeouts, fewer client disconnects), exposes Prometheus metrics, adds pre/post-promote hooks and file fetch/restore for WAL/config recovery, and drops legacy Python2 support.
