             Summary: Use unfiltered hosts list to build token ring
                 Key: CASSGO-124
                 URL: https://issues.apache.org/jira/browse/CASSGO-124
             Project: Apache Cassandra Go driver
          Issue Type: Improvement
          Components: Core
            Reporter: João Reis


Token ring in token aware policy is built from the internal host list that is maintained via AddHost() and RemoveHost() methods of the policy interface. These methods are only called for hosts that were not filtered by a HostFilter.

This creates a lot of complexity (and therefore edge cases) when building the token ring because the method doesn't have access to all the host metadata.

We should make the token aware policy retrieve the unfiltered host list from the driver when building the token ring but we need to be careful to ensure that the policy only picks hosts for queries that were already filtered.
