jiaan.geng created SPARK-39162:
----------------------------------

             Summary: Jdbc dialect should decide which function could be pushed 
down.
                 Key: SPARK-39162
                 URL: https://issues.apache.org/jira/browse/SPARK-39162
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
    Affects Versions: 3.4.0
            Reporter: jiaan.geng


Regardless of whether the functions are ANSI or not, most databases are 
actually unsure of their support.
So we should add a new API into JdbcDialect so that Jdbc dialect should decide 
which function could be pushed down.
