             Summary: [C++] Improved declarative compute function / kernel development framework, normalize calling conventions
                 Key: ARROW-8792
                 URL: https://issues.apache.org/jira/browse/ARROW-8792
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Wes McKinney
            Assignee: Wes McKinney
             Fix For: 1.0.0


I'm working on a significant revamp of the way that kernels are implemented in the project as discussed on the mailing list. PR to follow within the next week or sooner

A brief list of features:

* Kernel selection that takes into account the shape of inputs (whether Scalar or Array, so you can provide an implementation just for Arrays and a separate one just for Scalars if you want)
* More customizable / less monolithic type-to-kernel dispatch
* Browsable function registry (see all available kernels and their input type signatures)
* Central code path for type-checking and argument validation
* Central code path for kernel execution on ChunkedArray inputs

There's a lot of JIRAs in the backlog that will follow from this work so I will attach those to this issue for visibility but this issue will cover the initial refactoring work to port the existing code to the new framework without altering existing features.
