--------------------------------
Summary: Minimum parallelization width not respected in group scans
Key: DRILL-4415
URL: https://issues.apache.org/jira/browse/DRILL-4415
Project: Apache Drill
Issue Type: Bug
Components: Server
Reporter: MinJi Kim
Even if the minimum parallelization widith is set to > 1 value, this value is
not always respected.
For example, in AggPruleBase, the decision to do two phase aggregation
(create2PhasePlan) only takes into account the number of rows. So, if table is
small enough, even if the width is set to > 1 value, the plan will ignore the
minimum width request.
