The Corosync/Pacemaker framework which is part of the LinuxHA stack can be used to provide monitoring and automatic failover capabilities. Now with streaming replication in place, it makes sense to use this robust infrastructure for PostgreSQL master and its replica handling. The open source pgsql resource agent also does this now. This talk will talk about using Corosync/Pacemaker with Postgres. The talk will be on the following lines: Introduce the Corosync/Pacemaker LinuxHA stack and talk about its features Talk about PostgreSQL 9 and the high availability requirements Talk about how streaming replication helps meet these requirements Talk about how using Virtual IP and the Corosync/Pacemaker resource agents, a robust high availability solution can be provided by using Corosync/Pacemaker is a great platform to use for HA and talking about it at PGCon will raise awareness about it. |
