Hello together, sorry for the placement of this thread in this MySQL generalls topic. Was not sure where to post :/ I try to understand how to maintenance a database in the MariaDB World. But to be honest i have never seen before a bad technical documentation like from MariaDB. I located tasks like using ANALYZE TABLES or OPTIMIZE TABLE. Are there any other maintenance task that a DBA should operate? Some keywords explicit to MariaDB would be enough, please no general answers like reindexing or defragmenting. Thanks. Kind Regards from Germany.
