Sure, created CASSANDRA-4905. I understand that these tombstones will be still streamed though. Thats fine with me.
Do you mind if I ask where you stand on making... - ... ExpiringColumn not create any tombstones? Imo this could be safely done if the columns TTL is >= gcgrace. That way it is ensured that repair ran and any previous un-TTLed columns were overwritten. - ... ExpiringColumn not add local timestamp to digest?
