MySQL F.A.Q

What is the difference from MySQL and YML?

With MySQL you can sync placeholders across your servers.

What is a Main Server?

The main server is the server that put his config's placeholders in the database. The other servers will get the placeholders from the database.

Will the MySQL cause lag?

No

If I use MySQL are the config's placeholders read?

Yes, if the server is not a main server you'll have the database's placeholders and the config's placeholders.

How can i delete all my config's placeholders to use only database placeholders?

Just delete all placeholders

placeholders:
  # Nothing here ツ
