ufunc specifications

[jreback]

looks scipy encapsulated lots of function type things here: scipy/scipy#6509

we eventually will want to enable things like this as well for ufunc like things that can be processed efficiently via the c++ code.

This is cool. I think we'll want to have a similar low level callable interface for functions that utilize pandas2's C++ API

[jreback]

yep. arguably this interface should exist even lower down the chain (e.g. in pyarrow) or utilities. maybe even get scipy to use it :>

[wesm]

Yeah, definitely. Having a native callable API for Arrow data in C++ (that writes output into preallocated memory, or uses one of the builder classes, e.g. for strings) would be very nice
