[jira] [Created] (SPARK-38593) Incorporate numRowsDroppedByWatermark metric from SessionWindowStateStoreRestoreExec into StateOperatorProgress

L. C. Hsieh created SPARK-38593:
-----------------------------------

             Summary: Incorporate numRowsDroppedByWatermark metric from SessionWindowStateStoreRestoreExec into StateOperatorProgress
                 Key: SPARK-38593
                 URL: https://issues.apache.org/jira/browse/SPARK-38593
             Project: Spark
          Issue Type: Improvement
          Components: Structured Streaming
    Affects Versions: 3.3.0
            Reporter: L. C. Hsieh


Although we added `numRowsDroppedByWatermark` to `SessionWindowStateStoreRestoreExec`, but currently only `StateStoreWriter` will be collected metrics for `StateOperatorProgress`. So if we need `numRowsDroppedByWatermark` from `SessionWindowStateStoreRestoreExec` to be used in streaming listener, we need to incorporate `SessionWindowStateStoreRestoreExec` into `StateOperatorProgress`.
