[jira] [Created] (IMPALA-15097) Show runtime filter effectiveness in plan-graph.py

Quanlong Huang created IMPALA-15097:
---------------------------------------

             Summary: Show runtime filter effectiveness in plan-graph.py
                 Key: IMPALA-15097
                 URL: https://issues.apache.org/jira/browse/IMPALA-15097
             Project: IMPALA
          Issue Type: Improvement
            Reporter: Quanlong Huang
         Attachments: query-plan1.svg, rf_profile.txt

When verbosity is larger than 0, plan-graph.py generates nodes and lines for runtime filters. It'd be helpful to show ineffective runtime filters, e.g., by using dash lines.

It'd be more helpful if we should how many files/rows, etc. are skipped by the filter.

Uploaded an example profile and the generated svg file. The command is
{code:java}
bin/diagnostics/experimental/plan-graph.py -v1 rf_profile.txt | dot -T svg -o query-plan1.svg {code}
