----------------------------------

             Summary: pushDownPredicate failed to prevent push filters down to the data source.
                 Key: SPARK-36574
                 URL: https://issues.apache.org/jira/browse/SPARK-36574
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 3.2.0
            Reporter: jiaan.geng


Spark SQL also includes a data source that can read data from other databases using JDBC. 
Spark also supports the case-insensitive option pushDownPredicate.
According to http://spark.apache.org/docs/latest/sql-data-sources-jdbc.html, If set pushDownPredicate to false, no filter will be pushed down to the JDBC data source and thus all filters will be handled by Spark.
But I find it still be pushed down to data scoure.
