This change adds an entry to the config file where one can set the maximum pool size of the MySQL/MariaDB database connection. The default is set to 10, which is the default when not setting it at all anyway, so existing installations should see no change.
Allowing this value to be configurable can be useful if, for example, many Minecraft (or other) server instances are connecting to a database server which has a limited amount of connections it allows. On the other hand, increasing this value could help when connecting to a powerful database server with a highly loaded Minecraft server.
