Thanks for the corrections and info. Will check out that video. I could have sworn I had read these things about Umbra, but I suppose it was HyPer. Both interesting designs!

I am currently writing an on-disk B+tree implementation inspired by LMDB's blazing fast memory-mapped CoW approach, so I'm quite keen to learn what makes TUM's stuff fast.

Take a look at the opensource leanstore repository.

Very different approach from lmdb's mmap though. Not limited to single writer. Explicit buffer pool. Big difference from Umbra is fixed sized pages.
