Is there a tuning-primer.sh script, or something similar, compatible with MariaDB and capable of determining optimalness of MariaDB-specific features?
Answer Answered by colin charles in this comment.
tuning-primer.sh and mysqltuner.pl should just work with MariaDB.
However, it won't expand on the MariaDB features like all the new optimizer fixes in MariaDB 5.3 for example.
Is this something you would be interested in working on? Or something you would like to see?
