Peter Schuller commented on CASSANDRA-4417:
-------------------------------------------
@Sylvain I know it wouldn't be correlated with the *same* node; I was referring
to uncontrolled shutdowns in general in the cluster.
@Omid: Presumably the premise was that the mutation goes through the commit log
on the leader prior to replication. I'm not sure if this is the case, but if it
is, then it should work.
@jbellis FWIW, our counter use-cases are such that going commit log synch is
probably not feasable due to very high write throughput. Doesn't mean other
people's use-cases are the same, and of course I *fully* support the idea of
being correct by default (as opposed to performant by default).
@Sylvain again: I agree about refreshing nodeid on every unclean restart being
potentially dangerous. Counters are already huge due to the size of counter
shards, and refreshing nodeids in any situation which might result in en-masse
refreshment can definitely be dangerous both from a CPU usage perspective as
well as a disk space one.
