zanmato1984 opened a new pull request, #47297: URL: https://github.com/apache/arrow/pull/47297
### Rationale for this change A rework of #40223 using a more systematic alternative. ### What changes are included in this PR? Introduce a structure `MatchConstraint` for applying extra (and optional) matching constraint for kernel signature matching, in additional to simply input type checks. Also implement two concrete `MatchConstraint`s for binary decimal arithmetic kernels, to suppress exact match even if the input types are OK, for example, by requiring all decimal must be of the same scale for `add` and `subtract`, and s1 >= s2 for `divide`. This should also be a fundamental enhancement to further resolve similar issues like: * #35843 * #39875 * #40911 * #41011 * #41336 ### Are these changes tested? UT included. ### Are there any user-facing changes? New public class `MatchConstraint`. -- This is an automated message from the Apache Git Service.
