wuyi created SPARK-28867:
----------------------------

             Summary: InMemoryStore checkpoint to speed up replay log file in HistoryServer
                 Key: SPARK-28867
                 URL: https://issues.apache.org/jira/browse/SPARK-28867
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 3.0.0
            Reporter: wuyi


HistoryServer now could be very slow to replay a large log file at the first time and it always re-replay an inprogress log file after it changes. we could periodically checkpoint InMemoryStore to speed up replay log file.
