    Apache RocketMQ Past, Present, and Future - 厉启鹏 === {%hackmd LcL4-VI0SGitSiINTuy4rA %} > 請從這裡開始 ## Overview ### Apache RocketMQ - 原生的Messaging Queue - 金融等級 - 億萬等級messaging peak - Alibaba open source, 同Kafka為Apache頂級項目 ### 應用場景 (傳統) - Communication - Decoupled asynchronous - 把系統解耦,避免一個子服務掛掉其他也不能用 - Cut peak (削峰填谷) - 例如:雙11 - Log processing (最近的) - Data sync - IoT - 支持一些IoT協議,例如MQTT - IoT到雲端的入口 - MicroService - ServerLess ### RocketMQ優缺點 優點: - High Availability, Stable - 多topic的狀況時,表現比kafka穩定 - Messaging質量高, 低延遲 - 多topic同一個commitlog,順序列disk - Messaging堆積能力 - - 豐富的messaging類型 - pull mode / push mode、broadcasting / clustering - 佈署簡單 缺點: - 生態豐富度有待改善 - 語言的支持度還不夠完善,持續努力中 ## 使用案例 ### 平安銀行 - 平安銀行APP上每個數字都是一個子系統,透過RocketMQ推上app,達到異步解耦。 ### 弘康人壽 - 業務繁雜,各種業務用不同的框架/微服務。透過RocketMQ來做Edge Bus統一 ### 滴滴 - 離線使用kafka,即時的使用RocketMQ ## Community & Future City communities Ecosystem - 雲 - 邊 - 端 ###### tags: `COSCUP2019` `跨境合作 - COSCon (開源社)` `IB202`
