> 感觉和ns关系不大，我看每次如果有remain_server.id != server_list[pos].id 就会把remain_server.weight置0，那这时候就相当于从某个position的0位置开始按stride走，这时候的概率就不是权重的概率了吧。 我们服务权重变更很频繁，下游假设只有3个节点 权重为(110, 93, 87) stride为107，某一时刻权重微调，server_list顺序变了，那么按照现在逻辑remain_server.weight置0，都从pos的起始点走，那走到110上的概率接近2/3了吧。 我们上游节点有一百个，这种抖动现象就很明显 -- This is an automated message from the Apache Git Service.
