----------------------------------

             Summary: Find the right probe side fragment to any storage plugin
                 Key: DRILL-6792
                 URL: https://issues.apache.org/jira/browse/DRILL-6792
             Project: Apache Drill
          Issue Type: Improvement
          Components: Execution - Flow
            Reporter: weijie.tong
            Assignee: weijie.tong
             Fix For: 1.15.0


The current implementation of JPPD to find the probe side wrapper depends on the GroupScan's digest. But there's no promise the GroupScan's digest will not be changed since it is attached to the RuntimeFilterDef by different storage plugin implementation logic.So here we assign a unique identifier to the RuntimeFilter operator, and find the right probe side fragment wrapper by the runtime filter identifier at the RuntimeFilterRouter class.
