[Opensim-users] Interested in switching to MariaDB with TokuDB. Any issues?

[Chris]

Thanks James! :) I will definitely be doing all this in a test 
environment isolated from my main production server until I've worked 
the ins and outs of it... er... out. Would you happen to know if there 
are any issues importing a .sql dump that was taken from an install with 
the Federated Engine disabled to one where it is enabled? (And perhaps 
vice versa?) and using MySQL Admin to do it?
