DefaultLoadBalancingPolicy Class |
A load balancing policy designed to run against both DSE and Apache Cassandra clusters.
For most workloads, the query plan will be determined in a similar way to TokenAwarePolicy(DCAwareRoundRobinPolicy).
For graph analytics queries, this policy sets the preferred analytics graph server previously obtained by driver as the first host in the query plan. After this host, the query plan is the same as the one returned for other workloads.
