Wes McKinney updated ARROW-8969:
--------------------------------
Description:
We are instantiating multiple versions of templates in this module for cases
that, byte-wise, do the exact same comparison. For example:
* For equals, not_equals, we can use the same 32-bit/64-bit comparison kernels
for signed int / unsigned int / floating point types of the same byte width
* TimestampType can reuse int64 kernels, similarly for other date/time types
* BinaryType/StringType can share kernels
etc.
