> Currently, client uses primary replicas for partition awareness:
> * Get primary replica per partition from server (*Map<Partition, Replica>*)
> * Compute target replica from key
> * If a direct connection exists to that replica, use it. Otherwise, use any other connection.
> We can improve performance for certain requests (RO transactions) by using non-primary replicas as well:
> * Get all replicas per partition from server (first = primary) (*Map<Partition, List<Replica>>*)
> * Compute target partition from key
> * Iterate over the list of replicas in original order to find an active direct connection
> In other words, "use primary replica if possible, otherwise use non-primary replica, otherwise use any connection".
