摘要: Techniques are described for performing filter and project operations. In an embodiment, a set of predicates that specify criteria filtering results to query is received. Based on particular predicate the predicates, result at least one portion column generated. The identifies rows within first satisfy predicate. Rows selected returned as based in part result. bitvector where each bit corresponds row identify whether satisfies
