I'm assigning the C++ component because this is only relevant to the C++ streaming execution engine. However, the tool itself need not be written in C++.
Ideally this tool, given the exec plan log generated by ARROW-15061, the tool will generate some kind of flame chart.
A basic description of the process should be added to the execution engine docs or in a readme somewhere.
