I¹d recommend using Storm¹s State abstraction.

Subject:  Cassandra - Storm

Hi all,

Did anybody use Cassandra for the tuple storage in Storm? I have this
scenario: I have a spout (getting messages from RabbitMQ) and I want to save
all these messages in Cassandra using a bolt. What is the best choice
regarding the connection to the DB? I have read about Hector API. I used it,
but for now I wasn't able to add a new row in a column family.

Any help would be appreciated.

Regards,
Vanessa.
