Which is better MySQL and Mnesia in Ejabberd? -

-

hi working on ejabberd have 10k 20k concurrent user. better mysql , mnesia . or need use combination on them or other database.

mnesia not intended store large volume of data. should type of data requires quite large storage (several tens of thousands of record) , use mysql type of data. example, may relevant move roster , pubsub mysql.

you decide prepare large growth , put can directly in mysql.
