Summary: [C++] Add profiling / tracing for exec plan
Key: ARROW-14000
URL: https://issues.apache.org/jira/browse/ARROW-14000
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: Weston Pace
At a minimum we should be able to see how much time is spent in each node.
Other nice reports to see:
* Bandwidth vs. time for each operator
* Some visualization of threading / parallelism
This should be done in tandem with / on top of ARROW-12671
