Deploy and Host Postgres HA on Railway
Patroni based High Availability system for Postgres
About Hosting Postgres HA
Replicates all data from primary to 2 secondary postgres nodes. Managed by Patroni to ensure there is only one leader at a time, using etcd as distributed consensus primitive for election.
Automatically fails over to a secondary if primary is unavailable (while invalidating primary's lease on writes).
Common Use Cases
- Database replication
- Failover in case primary goes down
- Avoiding split brain in HA systems
Dependencies for Postgres HA Hosting
- Etcd cluster (3 nodes) for election
- PostgreSQL as database primitive
- Patroni as HA mechanism, managing leadership (write leases)
- HA Proxy to proxy connections to the leader
Deployment Dependencies
Why Deploy Postgres HA on Railway?
