Nothing Cassandra specific that I am aware of. Do you have any ops automation such as chef
or puppet ? 

Data Stax make their chef cook books available here

(in case your keys in one environment need to be a different value in another environment,
for example, you have a client_id based on an account number.  The account number exists on
dev and prod, but the client_id is different.  Want to let a dev write a mutator plugin to
 update the key prior to it writing to the destination.
