Subject Re: Downtime-Limit for a node in Network-Topology-Replication-Cluster?
Date Tue, 27 Oct 2015 21:27:02 GMT

Would you mind to elaborate further on this? I am a little concerned that
my understanding (nodetool repair is *not* the only way one can achieve
consistency) is not correct. I understand that if people use CL < QUORUM,
nodetool repair is the only way to go, but I just cannot see how can that
be the only way irrespective of everything else.

Thanks in advance for your input!
