and can be handled by relation
.
A pair of Seq[Expression]
and Seq[Filter]
. The first element contains all Catalyst
predicate Expressions that are either not convertible or cannot be handled by
relation
. The second element contains all converted data source Filters that
will be pushed down to the data source.
Tries to translate a Catalyst Expression into data source Filter.

if the input Expression is convertible, otherwise a None
