Recommended database engine with asterisk realtime?

Hi,

Is there any recommended database engine for using MySQL as backend for realtime?
What would be a better fit with Asterisk InnoDB or MyISAM?
I’d like to know what most users are using.

I use a mix. If the table is mainly for reading, I use MyISAM. If there will be some writing, I’ll use InnoDB. MyISAM doesn’t support transactions, but it’s faster. Volatile tables could use Memory, but I don’t have any.

Thanx a lot , I’m using InnoDB for cdr and MyISAM for all others.
