I am seeing unexpected behavior: consistency level ONE increases read latency 99th percentile to ~108ms (95th percentile to 5ms-90ms) up from ~5ms (99th percentile) when using LOCAL_ONE.
I am using DSE 5.0 with Datastax client 3.0.0. The client is configured with a TokenAwarePolicy wrapping a DCAwareRoundRobinPolicy with usedHostsPerRemoteDc set to a very high number. Cassandra cluster has two datacenters. I would expect that when the cluster is operating normally (all local nodes reachable), ONE would behave the same as LOCAL_ONE. The Does anyone know why this is not the case?
