Subject Re: average row size in a cassandra table

For rough estimate, I’ve seen the following pattern.

Sudo code
Do queries by token range at random.

Select asjson * from table;

Take the length of json string of each row.

Perform average.

(which can be found from nodetool tablehistograms), since a partition can have many rows.
I am looking for row size.
