<p>通过推拉结合的方式可以保证所有用户收到的消息展示顺序一致。细心的读者可能会有疑问，如果聊天信息流里有自己发送的消息，那么可能与其他的人看到的不一致，这是因为自己的消息展示不依赖拉取，需要即时展示，给用户立刻发送成功的体验，同时其他人也可能也在发送，最终可能比他先入库，为了不出现信息流中间插入消息的用户体验，只能将他人的新消息追加在自己的消息后面。所以如果作为发送者，消息顺序可能不一致，但是作为纯接收者，大家的消息顺序都是一样的。</p>

<p><strong>初始打开群</strong>：由于用户端采用H5开发，用户端没有缓存，没有能力缓存最近的已读消息游标，因此这里完全需要服务端来统计，在打开群时下发最新的聊天信息流和未读数，下面具体讲下这个场景下该怎么设计。</p> <p><br>既然由服务端统计未读数，那么少不了要保存用户在某个群里已经读到哪个消息，类似一个游标，用户已读消息，游标往前走。用户已读消息存储表设计如图7所示：</p> </section> <p><br></p> <section style="text-align: center;margin-top: 10px;margin-bottom: 10px;line-height: 0;">

的群里，最新的已读消息是id=1022消息，那么可以通过下面的SQL来统计他在这个群里的未读数：<br><span style="background-color: rgb(204, 204, 204);">select count(1) from msg_info where groupId = 89 and id &gt; 1022</span>。但是事情并没这么简单，一个用户有很多群，每个群都要展示未读数，因此要求未读数统计的程序效率要高，不然用户体验就很差，很明显这个 SQL 的耗时波动很大，取决于 offset 的位置，如果很靠后，SQL 执行时间会非常长。笔者通过2个策略来优化这个场景:</p> </section> <p><br></p> <section style="margin-top:

<section style="font-size: 13px;"> <ol class="list-paddingleft-1" style="padding-left: 40px;list-style-position: outside;">

MySQL 是比较低效的，因此笔者的方案是在 Redis 里设计一个有界的ZSET结构。</p></li> </ol> </section> </section> </section> <p><br></p> <section style="text-align: center;margin-top: 10px;margin-bottom: 10px;line-height: 0;">

class="list-paddingleft-1" style="padding-left: 40px;list-style-position: outside;"> <li><p><strong>消息发送风暴</strong>：极端情况下，用户同时发送消息，假设服务端承载住了这些流量，那么瓶颈其实在用户端，第一用户端会经历网络风暴，网卡带宽能否支撑是一个大问题；第二假设网卡能通过这些流量，用户端上百万条消息该如何展示，要是瞬间刷出这些消息，用户端 CPU能否撑住又是个问题，即使能抗住用户体验也很糟糕，根本就看不清消息，一直在飞速刷屏。因此服务端可以在发送消息风暴时做好限流、丢弃策略，给到用户友好的提示。</p></li> <li><p><strong>消息提醒风暴</strong>：一条新消息的产生，就要推送提醒消息百万次，对服务器来说，要考量整体推送完成的时效性，如果时效性差，对有些用户来说，就是消息需要较长时间才刷出来，出现明显的延迟。新消息持久化后，群组服务 HTTP 回调一组连接服务，单群百万在线用户，需要50台连接服务集群，那么回调50次，为了保证时效性，因此这里要并发回调，并设置合理的线程池，然后连接服务收到回调后也需要并发完成对群用户的新消息提醒推送。</p></li> <li><p><strong>消息拉取风暴</strong>：连接服务收到拉取消息事件，需要去群组服务获取消息详情，QPS 就非常高了，理论上集群达到 100wQPS，20台群组服务，那么每台群组服务就是 5wQPS。这里的策略是在链路前端连接服务上进行流量过滤，因为用户都是请求同一个群的同一条消息或附近的消息，那么就可以在连接服务里设计群消息的本地缓存，所有用户都只从本地缓存里读，如果本地缓存里没有，就放一个线程去群组服务请求加载缓存，其他线程同步等待，这样就大大降低了打到群组服务的 QPS。</p></li> </ol>

<p>如果某一个时刻，推送消息的数量比较大，且群同时在线人数比较多的时候，连接服务层的机房出口带宽就会成为消息推送的瓶颈。</p> <p><br>做个计算，百万人在线，需要5台连接服务，一条消息1KB，一般情况下，5台连接服务集群都是部署在同一个机房，那么这个机房的带宽就是1000000*1KB=1GB，如果多几个超大群，那么对机房的带宽要求就更高，所以如何有效的控制每一个消息的大小、压缩每一个消息的大小，是需要思考的问题。</p> <p><br>经过测试，使用 protobuf
