Oh, so this is source code for "JET blue" under MIT license. For now without comments, tests and build scripts - but that's comming.

Looks a bit like Microsoft's c++ toolkit that serves a similar use as lmdb, I guess? (although jet seems to do more than "just" db).

Looks like it's slightly more abstract than LMDB, in LMDB you're given sub-databases on which to implement your own index, this sounds like it handle some of the boilerplate as part of the framework. The mention of support for schemaless in the README suggests it might possibly also define row structures and stuff like that
