Yuki Morishita commented on CASSANDRA-8217:
-------------------------------------------
I agree this can be useful.
We use repair sesion ID for snapshot name right now, so I think what we need to
do is making it somehow unique among each snapshot.
> Fail snapshot based repair if Merkle tree does not use the same snapshot

> Snapshot based repair rely on having a snapshot on each replica. If for some
> reason, snapshot is not found or is different, we should fail the repair.
> This will avoid streaming lot of data around.
