-----------------------------------

             Summary: [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


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 arrays expressions
* 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.
