In this blog post, we’ll provide an overview of the new MySQL 8.0 RESOURCE_GROUP feature.

One great new feature introduced in MySQL 8.0 that – from my point of view – requires attention is RESOURCE_GROUP.

Short disclaimer: I want to point out that MySQL 8.0 is not GA yet, so it is possible for the MySQL 8.0 RESOURCE_GROUP implementation to change in features and/or behavior.

I’ve used MySQL Community Server 8.0 RC, and everything mentioned below applies to this MySQL version.

In this post, I will quickly look at this feature and summarize what it’s for, how it makes the DBA’s life a little bit easier and highlight some known limitations.

The MySQL documentation describes it as follows:

Now, create one test1 table and add 3 records in galera cluster.

MariaDB [nil]> select * from test1;

| id   | name      |

Starting with MySQL 8.0.4, we are changing the default authentication plugin for MySQL server from mysql_native_password to caching_sha2_password. Correspondingly, libmysqlclient will now use caching_sha2_password as the default authentication mechanism, too.

Why did we do it?

The advantage of mysql_native_password is that it support challenge-response mechanism which is very quick and does not require encrypted connection.…
