PostgreSQL is an advanced open source database that is completely community driven. Continuous development and performance improvements while making it feature rich gave PostgreSQL a great market penetration. When a database server is deployed in production, it is important to achieve several 9's of availability. It starts with a replication setup that is stable and some tool that could manage a failover transparent to application. This talk starts with a list of replication types in PostgreSQL followed by a detailed understanding of some of the widely used open source tools for high availability and automatic failover in PostgreSQL.
** Following topics will be discussed during this talk - **
- 1. How the implementation of HA differs for each type of replication available in PostgreSQL
- 2. How to combine HAproxy with etcd plus a detailed explanation of the RAFT Algorithm for HA using Patroni.
- 3. What is Patroni, pgpool-II and repmgr and how can they be helpful.
- 4. Some other tools admins may wish to explore.
- 5. What are the tools and solutions that help you achieve automatic failover in AWS and other cloud-based environments.
- 6. How to avoid huge data loss during failover.
