But this works only if the database is used by only one process.

Ah. When you said "concurrent safe", I thought you meant within the application. You're looking for something like thishttp://hackage.haskell.org/cgi-bin/hackage-scripts/package/anydbm .

Or even HApps-State (http://happs.org/) for moar 0v3rk1ll, of which you can never ever have enough.

HAppS-State doesn't currently solve the problem of the database being used by more than one process (does it?) In the current stable version, it basically maintains its data in-memory and keeps a checkpointed transaction log.

After watching the BayFP presentation I assumed that they've got cross-master synchronising going, and that's nearly a year old news now. Merely synchronising processes is trivial if you can do that. If the HAppS documentation wasn't as lacking as it is or I'd have more time, I would know more about this. -- (c) this sig last receiving data processing entity.
