Genmao Yu created SPARK-31677:
---------------------------------

             Summary: Use KVStore to cache stream query progress
                 Key: SPARK-31677
                 URL: https://issues.apache.org/jira/browse/SPARK-31677
             Project: Spark
          Issue Type: Improvement
          Components: Structured Streaming
    Affects Versions: 2.4.5, 3.0.0
         Environment: 1. Streaming query progress information are cached twice in *StreamExecution* and *StreamingQueryStatusListener*.  It is memory-wasting. We can make this two usage unified.
2. Use *KVStore* instead to cache streaming query progress information.
