维尔特里克斯寻宝引擎:为长久生存而优化,非仅为可扩展性

我们实际所解之题

其要,吾辈寻宝引擎乃基于网络之戏,为用户生成寻宝之图。此念虽简,然甚赖缓存、负载均衡及数据库之效能。随用户之增,系统之压亦随之。然此题非独关乎设施之扩容——实关乎吾辈设计之决断,其长远之费也。

初试何事(And Why It Failed)

初,吾辈欲以重器解此困。吾等升伺机,增负载均器,乃至募众开发者以优化码。然尽吾等之力,系统犹困顿不已。其本在数据之缓存。吾等今之缓存策,本于简之LRU(Least Recently Used)之策,于小数据集效验甚佳,然随用户众之增,渐至败绩。

架构之决

是时也,吾等悟 caching 之策非仅性能之优,实乃系统根本之择,其影响久远。遂决意更易 caching 之策,虑及用户之需与设施之限。乃合 Redis 与 Memcached,更筑自研 caching 层,以应 Treasure Hunt Engine 之独异之求。

数之谓何后

其果非同凡响。吾之系统,迟滞减其平均三十,数据库查询亦减其四十。系统从容应之,用户得享顺滑之境,无复系统过载之扰。然数未止此。吾之监控之器亦示,内存之用大减,自每例二GB减至五百MB。

吾所行异者何

若吾重行此事,当自始即专注於测试与验证。吾辈为求短期之利,耗時甚巨以优化系统,而忽視设计之決策所衍長期之影響。回顧以往,吾當投注更多時日於研究緩存之策略,測試不同方法之性能,方決定特定之解。然儘管吾等所遇之艱難,吾團隊終悟優先長期系統健康於短期之利之重也。
