What is the best way to delete column data from a Cassandra cluster after it is backed up with snapshots (using Priam or otherwise) to a stable storage?
We dont want to use the TTL option, since we would like to restore the backed-up data in the Cassandra cluster at a later time. Setting a TTL would enable the tombstone marker, which would make it impossible to restore data. What are the available options in Cassandra 1.2.5 in particular? Thanks!
