From the communication with a lot of TX, there are still many people do not understand the charging policy of MySQL. Let me give you a brief introduction.

First of all, MySQL is divided into Enterprise Edition and Community Edition (community server)

MySQL AB provides technical support only for the enterprise version, not for the community version.

The community version is free.

There are two kinds of authorization methods for enterprise MySQL, one is GPL, the other is commercial authorization of AB. If your project is open source and follows the GPL protocol, you can use the enterprise version for free. If it is a commercial project, you need to pay for it if you use the enterprise version.
