PGCluster 之一 setup

超、凢脫俗 2023-02-18 01:45 26阅读 0赞

PGCluster is a **multi-master** and synchronous replication tool of PostgreSQL based on **shared-nothing** architecture, developed by Atsushi Mitani and PGCluster developer’s team.

The lead developer of pgCluster has moved on to **pgCluster2**, and all development on pgCluster has halted. While pgCluster’s code is not fully mature, it is being used in production at a few sites.

A complete pgcluster requires **at least 6 machines** (3 database servers, 2 load balancers and a monitoring/failover controller). Also, it requires modifications to PostgreSQL core, so the Postgres version of pgCluster is always behind the mainstream version.

看上去已经停止开发了。
