EDB Postgres Distributed The Next Generation of Postgres High Availability
EDB Postgres Distributed is a next-generation solution designed to enhance high availability (HA) for Postgres databases. Traditional Postgres HA methods, such as physical streaming replication, have limitations in terms of downtime during upgrades and slow failover processes. EDB Postgres Distributed overcomes these issues by using a multi-master architecture with bidirectional replication (BDR) and High Availability Router for Postgres (HARP). This setup allows for near-zero downtime, even during maintenance, and ensures 99.999% availability. It also supports rolling upgrades, automatic DDL and DML replication, and advanced conflict resolution, making it ideal for critical, always-on applications.
