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

The MySQL documentation describes it as follows:

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.…
