Antoine Pitrou commented on ARROW-8894:
---------------------------------------
[~icook] You may want to consolidate this with your own umbrella issues :)
> [C++] C++ array kernels framework and execution buildout (umbrella issue)
> -------------------------------------------------------------------------
>
> Key: ARROW-8894
> URL: https://issues.apache.org/jira/browse/ARROW-8894
> Project: Apache Arrow
> Issue Type: New Feature
> Components: C++
> Reporter: Wes McKinney
> Priority: Major
>
> In the wake of ARROW-8792, this issue is to serve as an umbrella issue for
> follow up work and associated "buildout" which includes things like:
> * Implementation of many new function types and adding new kernel cases to
> existing functions
> * Adding implicit casting functionality to function execution
> * Creation of "bound" physical array expressions and execution thereof
> * Pipeline execution (executing multiple kernels while eliminating temporary
> allocation)
> * Parallel execution of scalar and aggregate kernels (including parallel
> execution of pipelined kernels)
> There's quite a few existing JIRAs in the project that I'll attach to this
> issue and I'll open plenty more issues as things occur to me to help organize
> the work.
