Bi-Directional Replication for PostgreSQL

Bi-Directional Replication for PostgreSQL (Postgres-BDR, or BDR) is the first open source multi-master replication system for PostgreSQL to reach full production status, developed by 2ndQuadrant and assisted by a keen user community. BDR is specifically designed for use in geographically distributed clusters, using highly efficient asynchronous logical replication, supporting anything from 2 to more than 48 nodes in a distributed database.
