When a session is created with one keyspace but queries are executed against a different keyspace (using keyspace.table syntax), the TokenAwareHostPolicy routes queries only to the primary replica and ignores ShuffleReplicas() setting because replica maps are only populated for the session's default keyspace. This causes hotspotting and reduced load distribution across the cluster for multi-keyspace workloads. This change implements lazy loading of replica maps in the Pick() method. When replicas are not found for a keyspace, the ensureReplicasForKeyspace() method is called to populate them on-demand using the session's existing KeyspaceMetadata capability. patch by Raj Ummadisetty for CASSGO-104 -- This is an automated message from the Apache Git Service.
