Hi all,
I read the function of ‘MaterializingIterator::MaterializeBlock’ carefully, and found that there is something we can do. If we adjust the ‘cur_idx_’ in ‘CFileSet::Iterator’ to the valid left of ‘dst->selection_vector’ after each loop of predicate evaluation, we could skip reading some unnecessary ‘data_block’ and that will help to speed up. Am I right? :) 何李夫 2017-04-10 16:06:24
