I'm potentially working with Cassandra as a store for some sensitive data. This data I want to be able to delete securely (securely meaning that the data is irrecoverable from the storage e.g similar to the shred command in Linux), I think there are 2 scenarios where this will need to happen.
1. When I delete a record (a tombstone is entered and the compaction will complete it) - does this securely remove it?
2. When I remove a snapshot using:
If anyone is able to shed some light on these 2 scenarios and whether or not they are deemed "secure", or if anyone has had to handle this requirement before, it would be greatly appreciated.
