--------------------------------------
Summary: FindLimit0Visitor should be applied after Calcite logical
transformation
Key: DRILL-4043
URL: https://issues.apache.org/jira/browse/DRILL-4043
Project: Apache Drill
Issue Type: Bug
Components: Query Planning & Optimization
Reporter: Sudheesh Katkam
Assignee: Sudheesh Katkam
FindLimit0Visitor optimization is applied after Drill logical transformation
(i.e. working on DrillRel node tree), and not after Calcite logical
transformation.
{{RelShuttle}} is meant to be applied on Calcite logical tree. So none of the
visitor methods except {{visit(RelNode other)}} are actually executed, and
search termination never happens.
