One misunderstanding is that "we should avoid memcpy as much as possible", but in fact Gluten isn't memory throughput bound yet. The sequential data read and write is a cheaper operation if the block size isn't too small (like several Bytes but not predictable, then the overhead is branch misprediction) or too large (like GB level). -- This is an automated message from the Apache Git Service.
