Github user fsauer65 commented on the issue: https://github.com/apache/spark/pull/22560 @maropu : This would certainly be another (perhaps better?) way to accomplish the behavior I'm looking for. However, I can't find where JdbcDialect is used on master to abstract connections, JDBCRDD is still using JdbcUtils to get a connection - does this exist on some other branch? : https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/jdbc/JDBCRDD.scala
