> In this case, Spark will resolve Or condition as one expression, and since this expr has reference of "id", then it can't been push down. Sorry, could you explain more here? The CNF process should break down `dt = 20190626 and id in (1,2,3)` to `Seq((dt = 20190626), (id in (1,2,3))`, and then these two sub-predicates will be processed in `groupExpressionsByQualifier`.
