HARDWARE IMPLEMENTATION OF THE FILTER/PROJECT OPERATIONS

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