BYTES, and the difference from the restore is the point.IMPORT_STATEMENTS_PER_CHUNK sizes a
restore chunk by statement COUNT because a replay WRITES, and rows written is the meter that binds
regeneration. An export writes nothing; what it spends is the memory to hold the encoded text and
the CPU to hex it, both proportional to bytes. Sized by statement count instead, 40
cfw_file_chunk rows -- 16 million characters -- would pass as one small chunk.
