Known Issues and Limitations

In the previous version of MaxScale, maxctrl was implemented as a JavaScript script that was run using the node interpreter on the platform. That introduced a dependency on node that earlier was not present. In this version of MaxScale, maxctrl is again a native executable without that dependency.

There are some limitations and known issues within this version of MaxScale. For more information, please refer to the Limitations document.
