Well under the 2,199,995-byte record ceiling rather than near it, for two reasons that both cost
something to learn: the ceiling is on the whole record, so the key and the integer columns count
against it too, and a chunk has to be readable AND writable inside one 10 ms invocation. 200,000
matches heap-store.ts, which settled on the same figure for the same reason.
Bytes per chunk.
