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

             Summary: SessionWindowStateStoreRestoreExec should provide numRowsDroppedByWatermark metric
                 Key: SPARK-38549
                 URL: https://issues.apache.org/jira/browse/SPARK-38549

          Issue Type: Improvement
          Components: Structured Streaming
    Affects Versions: 3.3.0
            Reporter: L. C. Hsieh


SessionWindowStateStoreRestoreExec filters out outdated inputs by watermark but it doesn't provide numRowsDroppedByWatermark. It makes users confused about stream query result.
