Release Highlights

Important fixes that improve stability and enhance the performance of ProxySQL, detailed release notes for ProxySQL 2.2.0 are available on the release page, a few noteworthy highlights can be found here:

  • In ProxySQL 2.1 an important change related to Prepared Statements was introduced for ProxySQL to process routing for Prepared Statements not only during PREPARE, but also during EXECUTE.
    • In ProxySQL 1.x – 2.0.x Prepared Statements that had already been PREPARED were always going to be routed to the target hostgroup that was determined during PREPARE, so they had to be “refreshed” after. For example, after updating ProxySQL Query Rules, they required to be re-PREPAREd in order to be routed to the new target hostgroup.
    • In ProxySQL v2.2 this has been further enhanced to support the processing of Query Annotations present in the statement also during EXECUTE.
  • Many many more fixes and updates!
