Weston Pace updated ARROW-13953:
--------------------------------
Description: ARROW-13952 introduced testing for the various computer kernel
signatures. Many kernels likely do not support union types (e.g. arithmetic or
string kernels) but there are a number of kernels that should operate on any
possible input type (e.g. drop_null, filter, take) and we should verify these
kernels work correctly with union types.
> [Python] Extend compute kernel type testing to also test for union types
