Stolon is a cloud native database manager and orchestrator for PostgreSQL. It functions as a high availability manager designed to automate failover, replication, and cluster management in distributed environments. The system coordinates synchronous and asynchronous data mirroring and uses a service discovery mechanism to dynamically detect database node addresses. It routes client traffic to the current primary instance through a proxy to maintain application access during role switches. The project covers disaster recovery through point-in-time recovery and the maintenance of multi-site st
