I recently started to look into Cassandra CDC implementation. One question that occurred to me is how/if TTL is handled for CDC. For example, If I insert some data with TTL enabled and expiring in 60 seconds, will CDC be aware of these changes 60 seconds later when the TTL expired? If not, then the cdc consumer won't know that the data has actually been deleted. A related question is where in the life cycle are expired TTLs getting detected and marked with tombstone? I am aware that during compaction, cells marked with tombstones will be deleted, but not sure if compaction will also look for cells with expired TTLs to mark them with tombstone?
