HAproxy A high-performance load balancer used to route traffic between the primary and standby PostgreSQL instances. This step-by-step guide covers setup, failover, and cluster management for a reliable PostgreSQL deployment. This blog covers tunable parameters that . conf. Patroni is an open-source python package that manages Postgres configuration. The key concept can be easily applied to a bigger number of nodes in In this post, support engineer Paul Namuag compares and contrasts PostgreSQL load balancing options including HAProxy, Pgpool-II, and others. Typically one master and multiple slaves in hot standby mode (asynchronous streaming replication). Patroni haproxy architecture What is Patroni? Patroni is an open source cluster management tool developed with python that provides a high availability solution for postgresql. In this blog, we have reviewed how HAProxy can help us to manage the traffic coming from the application into our PostgreSQL database. For maximum accessibility, Patroni HAProxy-based PostgreSQL Failover Setup In the case of a failure, failover is the act of automatically rerouting traffic or services from one server or system to another. We checked how it can be manually deployed and configured, and then saw how To summarize this blog presented a robust High Availability (HA) architecture for PostgreSQL leveraging Patroni, etcd, HAProxy, and PgBouncer to ensure minimal downtime and high resilience. Use Cloud SQL for PostgreSQL with HAProxy to deploy a load balancing solution for read queries, with automatic configuration and replica detection. Which can also act as a load balancer, PostgreSQL is a popular open-source relational database management system (RDBMS) used by many organizations to store and manage their data. It is a very Explore high-performing, fault-tolerant PostgreSQL setups with Patroni and HAProxy.
