Do you need highly performant counters that count accurately, without meaningful chance of over-count? If so, Cassandra's counters are probably not ideal. > We wanted to test what happens if one node goes down, so we brought one node > down in DC1 (i.e. the node that was handling half of the incoming writes). > ... > This led to a complete explosion of logs on the remaining alive node in DC1. I agree, this level of exception logging during replicateOnWrite (which is called every time a counter is incremented) seems like a bug. I would file a bug at the Apache JIRA. =Rob -- =Robert Coli AIM>ALK - rc...@palominodb.com YAHOO - rcoli.palominob SKYPE - rcoli_palominodb
