  • *Title : High availability and automatic failover in PostgreSQL on Kubernetes, On-premise and cloud using open source solutions. *

  • Abstract :

    • PostgreSQL is an advanced open source database that is completely community driven. Continuous development and performance improvements while maintaining a secondary focus on Oracle compatibility gave PostgreSQL a great market penetration. When a database server is deployed in production, we often wish to achieve several 9's of availability. Is that even possible with PostgreSQL ? What is the combination of tools that you could combine and implement to achieve High Availability (HA) and automatic failover in PostgreSQL ? How can we avoid data loss during such failover ? We'll address these questions and then some more in this talk.
  • *In this talk, we are going to discuss *

    • 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 and HA using Patroni.
    • 3. How to combine repmgr with keepalived to achieve HA.
    • 4. HA solution built for PostgreSQL on kubernetes.
    • 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.
