One thing which we, as developers of MariaDB, run into is that our personal database needs are not the same as many of our users. In fact, our needs are quite light compared to many.

But apart from talking to our customers, which are just a small percentage of the total MariaDB population, we wanted to have a way of finding out how MariaDB is used “in the real world”, so to speak. …
