-----------------------------------
Summary: [C++] Reduce generated code in
compute/kernels/scalar_compare.cc
Key: ARROW-8969
URL: https://issues.apache.org/jira/browse/ARROW-8969
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: Wes McKinney
Fix For: 1.0.0
We are instantiating 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.
