[jira] [Created] (SPARK-30269) Should use old partition stats to compare when analyzing partition

Zhenhua Wang created SPARK-30269:
------------------------------------

             Summary: Should use old partition stats to compare when analyzing partition
                 Key: SPARK-30269
                 URL: https://issues.apache.org/jira/browse/SPARK-30269
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.4.4, 2.3.4, 3.0.0
            Reporter: Zhenhua Wang
             Fix For: 2.3.5, 2.4.5, 3.0.0


It's an obvious bug: currently when analyzing partition stats, we use old table stats to compare with newly computed stats to decide whether it should update stats or not.
