Thanks. I had a super quick look. It would be nice if you could give a
high level overview on this (if you're going to spend a lot more time on it).
One random thought, maybe it's better to have a daemon for external
odb right from the start (one for all odbs, or one per odb, I don't
know). It could do fancy stuff like object caching if necessary, and
it can avoid high cost handshake (e.g. via tls) every time a git
process runs and gets one object. Reducing process spawn would
definitely receive a big cheer from Windows crowd.
Any thought on object streaming support? It could be a big deal (might
affect some design decisions). I would also think about how pack v4
fits in this (e.g. how a tree walker can still walk fast, a big
promise of pack v4; I suppose if you still maintain "pack" concept
over external odb then it might work). Not that it really matters.
Pack v4 is the future, but the future can never be "today" :)
