ProxySQL is engineered with a sophisticated multi-core framework that can handle hundreds of thousands of simultaneous connections while efficiently multiplexing them across numerous servers. It offers sharding capabilities based on user, schema, or table through its sophisticated query rule engine or customizable plugins. The development team is relieved from the need to alter queries generated by Object-Relational Mappers (ORMs) or packaged applications, as ProxySQL's dynamic query rewriting feature can adjust SQL statements as needed. The term "battle-tested" barely captures its resilience; ProxySQL has proven itself in the most demanding conditions. With performance as its core focus, the metrics speak for themselves. As an open-source, high-performance, and highly available proxy for MySQL and PostgreSQL, ProxySQL serves as a powerful SQL proxy solution, acting as a crucial intermediary between database clients and servers. This extensive array of features is designed to enhance and simplify database operations, ultimately allowing organizations to maximize their database infrastructure's effectiveness. The capabilities of ProxySQL ensure that organizations can achieve unparalleled efficiency and reliability in their database management tasks.
