Introducing MariaDB MaxScale 2.2.1 Beta – automation, security and more!


We are happy to announce that  2.2.1 beta of MariaDB MaxScale, the next generation database proxy for MariaDB is now available. Beta is an important time in our release and we encourage you to download this release today!

The goal of this MariaDB MaxScale release is self-healing automation, hardened database security, preparing for new capabilities for the upcoming MariaDB Server 10.3 release, while at the same time, making it easier to manage.

MariaDB MaxScale 2.2.1 introduces the following key new capabilities:

MariaDB Server feature support:

  • Proxy protocol support for backend connections, a MariaDB Server 10.3 feature. This makes it easy to configure authorized use between the Client, MaxScale and Server.
  • PL/SQL Compatibility syntax support for upcoming MariaDB Server 10.3 support.
  • Support of window functions and CTEs processing.
  • Binlog router supports MariaDB 10 GTID at both the master and slave side.

Management Interface:

  • REST-API for obtaining information about and managing the resources of MaxScale.
  • MaxCtrl, a new command line client for administering MaxScale implemented using the REST-API, for managing an individual MaxScale as well as a cluster of MaxScales



  • MariaDB Server states are persisted, so in the case of a crash and a restart of MaxScale, it has the correct server state, quicker.
  • Monitor scripts are executed synchronously, so they can safely perform actions that change the server states.
  • Prepared statements are now parsed and the execution of read only ones will be routed to slaves.
  • KILL CONNECTION can now be used through MaxScale.
