> https://issues.apache.org/jira/browse/SPARK-37960 provides a new framework to represent catalyst expressions in DS V2 APIs.
> Because the framework translate all catalyst expressions to a unified SQL string and cannot keep compatibility between different JDBC database, the framework works not good.
> This PR reactor the framework so as JDBC dialect could compile expression by self way.
> First, The framework translate catalyst expressions to DS V2 expression.
> Second, The JDBC dialect could compile DS V2 expression to different SQL syntax.
