AngersZhuuuu removed a comment on issue #24973: [SPARK-28169] Fix Partition table partition PushDown failed by "OR" expression URL: https://github.com/apache/spark/pull/24973#issuecomment-506584232 @cloud-fan Since I am familiar with code about hive , I just looked about other strategies about scan data. How about we convert filter expression set to CNF in PhysicalOperation. Then change the way get partition expressions like below, since with CNF, just use **subSet** to judge is not enough: ` val partitionKeyFilters = ` ` ExpressionSet(normalizedFilters` ` .filterNot(SubqueryExpression.hasSubquery(_))` `.filter(_.references.subsetOf(partitionSet))`
