    Hi,
    
    How about taking it from the BoundStatement directly?
    
    ByteBuffer routingKey = 
    b.getRoutingKey(ProtocolVersion.NEWEST_SUPPORTED, codecRegistry);
    Token token = metadata.newToken(routingKey);
    
    In this case the b is the "BoundStatement". Replace codecRegistry & 
    ProtocolVersion with what you have. codecRegistry for example from the 
    codecRegistry = session.getCluster().getConfiguration().getCodecRegistry();
