I made a MariaDB Tuning course, and it's very important to test the system with real traffic and real data, simulate a Production server basically.
The data is easy to replicate, just a dump, or even replication for have the database updated. But how do you test your traffic for make statistics? You can't replicate your users and their consumption of the server's resources, can you?
Do you know any tool that I could use for simulating this traffic?
