AFAICT that is a 5 year old branch.  Is there a version of this based off of master that you can show asv results for?

A correction here: that branch has been updated several times over the last 5 years, and a last time two weeks ago when I started this thread, as I explained in the github issue comment I linked to: https://github.com/pandas-dev/pandas/issues/10556#issuecomment-633703160

In principle, this is pretty much exactly what the asvs are supposed to represent.

Well, I am repeating myself .. but I already mentioned that I am not sure ASV is fully useful for this, as that requires a complete working replacement, which is IMO too much to ask for an initial prototype.

But OK, the message is clear: we need a more concrete implementation / prototype. So let's put this discussion aside for a moment, and focus on that instead. I will try to look at that in the coming weeks, but any help is welcome (and I will try to get it running with ASV, or at least a part of it).

 

To come back to this: I cleaned up a proof-of-concept implementation that I started after the above discussed, and put it in a PR to view/discuss: https://github.com/pandas-dev/pandas/pull/36010
