Wes McKinney created ARROW-8792:
-----------------------------------
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.
