Abstract
The subject technology receives a first query plan, the first query plan including a set of statements, the set of statements including at least one statement with at least a reference to a particular column in a first table. The subject technology identifies a first predicate from the at least one statement, the first predicate corresponding to a join operation. The subject technology determines, for the particular column, a set of expression properties. The subject technology, based on the set of expression properties, determines a first derived predicate, the first derived predicate corresponding to a first filter operation. The subject technology generates a new operation based on the first derived predicate. The subject technology generates a new query plan based at least in part on the join operation of first predicate, the first derived predicate, and the new operation of the first derived predicate.
