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

Returns the hosts to use for a new query. The returned plan will first return replicas (whose HostDistance for the child policy is Local) for the query if it can determine them (i.e. mainly if IStatement.RoutingKey is not null). Following what it will return the plan of the child policy. |
