turi::query_eval::opt_split_contractive_expansive_projection Class Reference

#include <core/storage/query_engine/planning/optimizations/project_transforms.hpp>

Detailed Description

If a projection node results in more columns, but it is only choosing a subset of the columns, split it in to two. The optimizations are designed so that expansive projections move downstream, and contractive expansions move upstream.
