This actually looks really cool, but seems to have no support for concurrent modification or access. I'm presuming that in order to make this thread-safe you'd just need to lock the whole database.

Anybody aware of any thread-safe model layer for C?

sqlite 3.0 later seems to be thread-safe.

BTW, how's datadraw compare to sqlite?

Is there any opensource using this already? I'd love to see some examples in c++ with concurrent access.

Look at the bottom of the page :

- DataDraw (this project)

- gnetman - an netlist translation tool, compatible with gEDA

- BTSlave - a BitTorrent client

- NetFS - a BitTorrent replacement

I had noted them when I posted, they didn't seem very recent (or to be more precise... they don't seem very modern). The last few years have seen a proliferation of in memory databases.

Mmmm... this could be use as a kind of kdb+/q/j backend? I wish to build a language that be array/table based.

Something else like this?
