MySQL InnoDB Cluster – Compatibility Matrix

on

Recently during my several talks and trips to meet the MySQL Community and MySQL InnoDB Cluster, I realized that some important message was missing. I got a lot of questions about which version of Router or Shell people should use. There is some confusion about which version to use, it seems that people thinks they should use MySQL Shell 1.0.x and MySQL Router 2.1.x with MySQL 5.7 and use the 8.0.x version having the same version as MySQL 8.0. This is wrong !

In fact, whatever the version of MySQL InnoDB Cluster you are using, you should ALWAYS use the latest version of Router and Shell. Currently it’s 8.0.11. So yes, even if you use MySQL 5.7.22, you MUST use MySQL Router 8.0.11 and MySQL Shell 8.0.11.

Our development team works on the backward compatibility with the server and takes advantages of the new features when back-ported.

Let’s recap this with a simple matrix 😉
