# Rationale for this change
Row format is more cache-friendly for "row logic" operators, at the cost of
more computation involved while incorporating in vectorized engines like our
DataFusion. (there would be extra row <-> columnar conversions of course)
This work is to explore the usage of row-format as the in-memory records
buffer layout, for benchmark, test, and discussion purposes.
