             Summary: Tighten filter push down at Druid handler 
                 Key: CALCITE-1779
                 URL: https://issues.apache.org/jira/browse/CALCITE-1779

          Issue Type: Bug
            Reporter: slim bouguerra
            Assignee: Julian Hyde


Tighten filter push down at Druid handler , as a follow up of CALCITE-1777.
the approach will something like  parse the filter tree by visit every leaf and try to generate a druid filter, if we have a valid leaf druid representation the underline rel will be pushed otherwise it will not be pushed.
