The option to enable or disable predicate push-down into the JDBC data
source. The default value is true, in which case Spark will push down filters
to the JDBC data source as much as possible. Otherwise, if set to false, no
filter will be pushed down to the JDBC data source and thus all filters will be
handled by Spark. Predicate push-down is usually turned off when the predicate
filtering is performed faster by Spark than by the JDBC data source.

managing its own login and requiring user creds... :-/ Will have to live with
