> Project: Apache Drill
> Issue Type: Bug
> Reporter: Steven Phillips
> Assignee: Jacques Nadeau
>
> Currently, a minor fragment is run in a single thread, and parallelization is
> achieved by running multiple minor fragments. There are cases where we are
> limited in how much we can parallelize the leaf fragments due to the limited
> number of files/row groups. This can result in under-utilization of resources.
> This operator will allow the scan operator to run in parallel with the
> downstream operators in the leaf fragments, thus increasing cluster
> utilization, and reducing the duration of the leaf fragments in certain cases.
