I am interesting. I have been doing a lot of Mnesia based development
recently and have just started rereading the RDBMS code.
I think Mnesia is often under-estimated and can be used successfully in

Could you elaborate a little on this. I was running a study to possibly
revive the Berkeley DB backend idea. My goal is to be able to store huge
amount of data efficiently with a correct query time in Mnesia.

My interest goes to:
- Being able to make Mnesia even more versatile and configurable. Easy
to develop and pluggable (I mean configurable) storage back-end would be nice.
- Being able to support high volume of storage efficiently in Mnesia.
What would you think of adding a way to force storage in binary instead
of list through rdbms ? (This would reduce storage space).
