I would like to have some script where I first insert say 100 rows in a CF. Then reinsert the same data on 'server side' with new unique key. That will make it 200 rows. Then continue the exercise a few times till I get lot of records. I don't care if the column names and values are identical between the different rows. Just a lot of records generated for a few seed records. The rows are very fat. So I don't want to use any client side scripting that would push individual or batched rows to cassandra. Thanks for any tips.
