內(nèi)容簡(jiǎn)介

　　本書(shū)專為想要學(xué)習(xí)并掌握Apache Pulsar的讀者打造，是一本入門(mén)圖書(shū)。全書(shū)共有13章內(nèi)容。第1章和第2章，從生活實(shí)例中引入實(shí)時(shí)消息系統(tǒng)和事件驅(qū)動(dòng)的概念，幫助大家理解Apache Pulsar系統(tǒng)存在的必要性，以及Pulsar的獨(dú)特性和價(jià)值定位。第3章介紹了Pulsar在雅虎的起源故事、設(shè)計(jì)理念與應(yīng)用場(chǎng)景。第4章探究了Pulsar內(nèi)部的主要組件及其工作原理，幫助大家構(gòu)建對(duì)Pulsar的整體架構(gòu)認(rèn)知。第5章到第10章，詳細(xì)介紹了Pulsar消費(fèi)者、生產(chǎn)者的工作原理，應(yīng)用于生產(chǎn)和消費(fèi)消息且與第三方系統(tǒng)交互的框架Pulsar IO，以及Pulsar Functions、分層存儲(chǔ)、Pulsar SQL等Pulsar的獨(dú)特理念和關(guān)鍵特性。第11章與第12章，展示了如何在諸多環(huán)境中部署Pulsar，以及在運(yùn)維Pulsar的過(guò)程中需要關(guān)注的指標(biāo)。在第13章中，作者結(jié)合個(gè)人經(jīng)驗(yàn)闡述了Pulsar未來(lái)值得探索的領(lǐng)域和方向。本書(shū)配圖生動(dòng)形象，實(shí)例豐富，不僅提供了很多代碼示例，還提供了多篇附錄，以作參考。
