Weston Pace updated ARROW-15067:
--------------------------------
Labels: query-engine (was: )
> [C++] Add OT spans for the scanner
> ----------------------------------
>
> Key: ARROW-15067
> URL: https://issues.apache.org/jira/browse/ARROW-15067
> Project: Apache Arrow
> Issue Type: Sub-task
> Components: C++
> Reporter: Weston Pace
> Priority: Major
> Labels: query-engine
>
> There should be one span for each "read batch" and one scan for each "read
> file". The batch spans should be children of the file span.
> If possible it would be nice if the "read file" spans were children of the
> exec plan when the scanner is being used as a source node. I'm not sure if
> this is doable though since the scanner is often used outside the exec plan.
