Understanding Unfamiliar Tables in the MariaDB System Database

Here's what can cause you to see unfamiliar tables:

• MariaDB features: MariaDB may have features that MySQL (a close relative) doesn't. These features might add extra tables to the system database.
• Third-party tools: Some third-party tools you use with MariaDB might create their own tables in the system database to store information.

If you're concerned about a particular table, you can search online using the table name and "MariaDB" to see if you can find documentation about it. However, generally it's best to leave the system database tables alone unless you're a MariaDB administrator.

Similarly, third-party tools designed to work with MariaDB might add their own tables to the system database to store information specific to their functionality. These would also be created automatically when you install and configure the tool.
