------------------------------------
Summary: [C++][Compute] Refactor FunctionExecutor -> KernelExecutor
Key: ARROW-10468
URL: https://issues.apache.org/jira/browse/ARROW-10468
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Affects Versions: 2.0.0
Reporter: Ben Kietzman
Assignee: Ben Kietzman
Fix For: 3.0.0
FunctionExecutor currently handles dispatch to a kernel as well as allocation
and invocation of the kernel. In some contexts (such as a filter expression
bound to a specific schema) we only need to perform dispatch once, so
repeatedly dispatching to kernel is redundant. Refactor to a KernelExecutor
which is constructed from a pre-selected kernel.
