I’m pleased to say that we’ve just released Postgres-BDR 1.0, based on PostgreSQL 9.4.9.
This release contains significant improvements to DDL replication locking, global sequences, documentation, performance, and more. It also removes the deprecated UDR component in favour of pglogical.
It’s taken a lot of work to get to this point. This release sets the foundation to port BDR to PostgreSQL 9.6 and to enhance its high-availability capabilities, and I’m excited to be pushing BDR forward.
Bi-Directional Replication for PostgreSQL (Postgres-BDR, or BDR) is an asynchronous multi-master replication system for PostgreSQL, specifically designed to allow geographically distributed clusters. Supporting more than 48 nodes, BDR is a low overhead, low maintenance technology for distributed databases.
