ProxySQL is a high-performance proxy for MySQL and MySQL-compatible database servers such as Percona Server for MySQL and MariaDB. It acts as an intermediary for client requests seeking resources from the database. ProxySQL was created for the database administrator to solve complex replication topology issues. Percona distributes ProxySQL as a repackaged version of the upstream release, without making any code modifications.

You can download the original ProxySQL from GitHub. The ProxySQL documentation provides information on installing and running ProxySQL.

The ProxySQL Admin (proxysql-admin) tool simplifies the configuration of Percona XtraDB Cluster nodes with ProxySQL. ProxySQL Admin 2 supports Percona XtraDB Cluster without custom scripts.

The pxc_scheduler_handler tool can automatically perform a failover due to node failures, service degradation, or maintenance. This tool has features and capabilities that differ from the ProxySQL admin tool, so you should not use options from one tool in the other, as that may cause unintended results.

Release highlights

Compared to the previous ProxySQL 2.6.3 release, this release includes all improvements and bug fixes available in ProxySQL 2.6.4 and ProxySQL 2.6.5.

In this release, we are skipping ProxySQL 2.6.4. We are releasing ProxySQL 2.6.5, which is the latest ProxySQL release. This decision ensures that you receive the most up-to-date features and improvements.

  • Upgraded OpenSSL to version 3.3.1.

  • Added compatibility for Ubuntu 24 and Fedora 40.

  • The system now correctly handles the USE command when it ends with a semicolon. It removes any trailing semicolon automatically. Additionally, the system will now return an error if someone tries to use the USE command as part of a multi-statement query.

  • In versions 2.5.2 through 2.6.4, the stats_mysql_query_digest.digest feature generated lowercase output when it should have been uppercase.
