Muhammad Ali explains how load balancing works in Postgres:
Load balancing is a critical component of high availability clusters that optimises performance, scalability, and fault tolerance. By evenly distributing database connections across multiple servers, load balancing prevents bottlenecks, efficiently handles increased workloads and improves response time.
In this blog, we will explore how standby nodes contribute to efficient workload distribution and achieving optimal query execution by directing all read/select queries to these standby nodes.
Read on to see how you can use pg_cirrus to perform query load balancing.
