                 Key: SPARK-36424
                 URL: https://issues.apache.org/jira/browse/SPARK-36424
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 3.2.0
            Reporter: XiDuo You


In Ad-hoc scenario, we always add limit for the query if user have no special limit value, but not all limit is nesessary.

With the power of AQE, we can eliminate limits using running statistics.
