[verb] size-histogram to learn item size distribution #96
Description
It's easy to know the average item size (it's in the table metadata) but it's not so easy to know the histogram of item sizes. This verb would calculate that. How many items from 0-1kb, from 1-2kb, etc.
It would accept the usual where clause to be able to look at just how large a subset of items are. How big to my orders tend to be?
./bulk size-histogram --table t --where 'SK like "ORDER#%"'
