Postgres-BDR (Bi-Directional Replication for PostgreSQL) brings ground-breaking distributed database capabilities to PostgreSQL. BDR as a multi-master replication extension for PostgreSQL databases has been in full production status since 2014. In the complex environment of replication, BDR achieves efficiency and accuracy, ensuring very high availability of all nodes in a geographically distributed cluster.
An overview of BDR, including its features and their benefits, use cases, and deployment options, is available publicly in the Postgres-BDR white paper.
BDR 4.0 is the current release supporting v12-14 of PostgreSQL, EDB Postgres Extended Server (formerly 2ndQuadrant Postgres), and EDB Postgres Advanced Server. Advanced BDR features are only available with Extended Server (for PostgreSQL compatibility) and Advanced Server (for Oracle compatibility).
