Split read & write, route traffic to the right place, and achieve stable & reliable access to the PostgreSQL cluster.

Service is an abstraction to seal the details of the underlying cluster, especially during cluster failover/switchover.

Personal User

Service is meaningless to personal users. You can access the database with raw IP address or whatever method you like.

psql postgres://dbuser_dba:DBUser.DBA@10.10.10.10/meta     # dbsu direct connect
psql postgres://dbuser_meta:DBUser.Meta@10.10.10.10/meta   # default business admin user
psql postgres://dbuser_view:DBUser.View@pg-meta/meta       # default read-only user

Service Overview

We utilize a PostgreSQL database cluster based on replication in real-world production environments. Within the cluster, only one instance is the leader (primary) that can accept writes. Other instances (replicas) continuously fetch WAL from the leader to stay synchronized. Additionally, replicas can handle read-only queries and offload the primary in read-heavy, write-light scenarios. Thus, distinguishing between write and read-only requests is a common practice.
