Just to check Ninad. If you are using Cassandra-2.1 (native protocol v3) and the java driver version 3.0 or above, then you would be using client-side timestamps by default. https://github.com/datastax/java-driver/tree/3.x/manual/query_timestamps With client-side timestamps all client servers and all C* nodes must be kept tightly in-sync, as Elliot said. Monitoring and alerting on any clock skew on any of these machines is important. Also worth checking that any local_quorum requests are not accidentally go to the wrong datacenter. regards, Mick --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@cassandra.apache.org For additional commands, e-mail: user-h...@cassandra.apache.org
