LisPi (nprofile…2mzm) by the way, fyi, a Twitter engineer wrote an #LMDB backend for #git back in 2015.
https://lore.kernel.org/git/1435020656.28466.8.camel@twopensource.com/"The [LMDB] backend runs git for-each-ref about 30% faster than the files
backend with fully-packed refs on a repo with ~120k refs. It's also
about 4x faster than using fully-unpacked refs. "
The git devs then spent the next 5 years nitpicking the patch, literally to death. In 2020 the patchset died, the original author left twitter for a new job.
