# Proposed changes After vec_predicate, doris generates the array sel_rowid_idx for selected rows from 0/1 array ret_flags. This pr implements a short cut for 2 cases: - all rows are passed predicate - none row is passed Furthermore, if the 32-char part of ret_flags is 0 or 0xfffffff, the implementation also optimized.
