In September I will be present at the Percona Live Europe Amsterdam 2015 conference and present about the MySQL …

Sometimes, rarely, it happened that you got also a warning message, telling you that while the installation was successful, you could improve it by fine tuning this and that. No big deal.

Gone are those times. A clean …
