[jira] [Created] (CALCITE-1888) VolcanoPlanner should identify if transformed node and original node are identical

Atri Sharma created CALCITE-1888:
------------------------------------

             Summary: VolcanoPlanner should identify if transformed node and original node are identical
                 Key: CALCITE-1888
                 URL: https://issues.apache.org/jira/browse/CALCITE-1888
             Project: Calcite
          Issue Type: Improvement
            Reporter: Atri Sharma
            Assignee: Julian Hyde


VolcanoPlanner should identify that the transformed node and the original node are identical, hence should not fire the same rule again. This would help avoid corner cases where VolcanoPlanner gets stuck in an infinite loop
