------------------------------------
Summary: [C++] Provide per-processor Executors to support pinning
workflows to a core
Key: ARROW-10544
URL: https://issues.apache.org/jira/browse/ARROW-10544
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Affects Versions: 2.0.0
Reporter: Ben Kietzman
For many workflows, there is a distinct performance advantage to avoiding
transfer of a task between processors. For example when iteratively processing
a small dataset keeping everything local to a single CPU can avoid churn in
split caches. Allowing each logical core to be accessible as an {{Executor}}
would be one way to give developers the requisite control.
