-------------------------------------------

Great idea! should be sure to add a throttle in the deletion to prevent trashing drives

> It should be possible to add a TTL to snapshots, after which it automatically cleans itself up.
> This will be useful together with the {{auto_snapshot}} option, where you want to keep an emergency snapshot in case of accidental drop or truncation but automatically remove it after a specified period when it's no longer useful. So in addition to allowing a user to specify a snapshot ttl on {{nodetool snapshot}} we should have a {{auto_snapshot_ttl}} option that allows a user to set a ttl for automatic snaphots on drop/truncate.
