Umair Shahid gives us the rundown on one mechanism to scale out Postgres:
As databases scale and user demands intensify, the challenge of maintaining performance increases. While PostgreSQL was originally designed (40 years ago!) to scale up, but increasing demands on the database have created the need to enable it to scale horizontally. PL/Proxy is a database partitioning system designed to simplify the process of distributing database loads across multiple servers. It acts as a transparent layer between the application and the database, enabling queries to be directed to the appropriate shard or partition based on predefined rules.
This article will dive into PL/Proxy, taking a look at its benefits, use cases, and best practices to enhance PostgreSQL’s performance through effective scaling.
