If your entire dataset in a keyspace or column family is deleted every
[small time period], then maybe use TRUNCATE?

Two caveats :

will leave undelivered hints untouched until 1.2.6
2) TRUNCATE will create a snapshot unless you (unsafely!!!!!!!
danger!!!!!!!!) disable this feature [1]

Alternately, perhaps a datastore with immutable data files is not for you? :D
