TokenAwarePolicy Class

A wrapper load balancing policy that adds token awareness to a child policy.

This policy encapsulates another policy. The resulting policy works in the following way:

  1. The Distance(Host) method is inherited from the child policy.
  2. The host yielded by the NewQueryPlan(String, IStatement) method will first return the Local replicas for the statement, based on the RoutingKey.
