As of Cassandra 0.8.1, are counter increments and decrements idempotent? If, for example, a client sends an increment request and the increment occurs, but the network subsequently fails and reports a failure to the client, will Cassandra retry the increment (thus leading to an overcount and inconsistent data)?
I have done some reading and I am getting conflicting sources about counter consistency. In this source ( http://cassandra-user-incubator-apache-org.3065146.n2.nabble.com/clarification-of-the-consistency-guarantees-of-Counters-td6421010.html), it states that counters now have the same consistency as regular columns--does this imply that the above example will not lead to an overcount? If counters are not idempotent, are there examples of effective uses of counters that will prevent inconsistent counts? Thank you for your help.
