Luís Ferreira commented on CASSANDRA-2686:
------------------------------------------
Maybe I misunderstood, but to get locks with ZK, every node has to make it's
presence known to ZK, and ask ZK to get a certain lock (which I think it's what
cages does). Can't this be a bottleneck?
I know consensus can't be achieved with one failing node, therefore the need
for something like ZK. Still, isn't there a way to do this using something like
hinted handoff?
Maybe I haven't explained correctly my idea. I'd like to have locks, but
maintain the general structure of a cassandra cluster, and change as little as
possible the kind of messages the nodes send.
