How should I think of the efficiency of a single operation? If there is one row that we are incrementing 10 counters in, will that cost about as much as incrementing a single counter in that row, or more like 10x?

(Note: Updating the same row n times, without batching, produces the same numbers as any other n operations without batching.)
