Omg epic. @stuhood definitely cherry-pick this to 2.14. Thoughts on 2.13? I'm hoping to do an RC tonight if I can get CI green. |
For sure |
It's not strictly needed, and skipping it can avoid a lot of IO. [ci skip-build-wheels]

DigestTrieto create all snapshots at once, instead of creating them individually[ci skip-build-wheels]
I restored the benchmark script from #14569 to test this. The results seem almost too good to be true, but here they are 馃
