@antonoal Thanks a lot for looking into this! As @rxin pointed out, we
currently infer these transitive predicates by looking at the data constraints
for each operator in the logical plan (please also see
https://github.com/apache/spark/pull/11665). Can you please add the
`InferFiltersFromConstraints` rule in `TransitiveClosureSuite.scala` and see if
it handles all your test cases?
