這篇文章主要介紹了Spring?Boot實(shí)戰(zhàn)解決高并發(fā)數(shù)據(jù)入庫(kù)之?Redis?緩存+MySQL?批量入庫(kù)問(wèn)題，本文通過(guò)圖文實(shí)例相結(jié)合給大家介紹的非常詳細(xì)，對(duì)大家的學(xué)習(xí)或工作具有一定的參考借鑒價(jià)值,需要的朋友可以參考下

前言

最近在做閱讀類(lèi)的業(yè)務(wù)，需要記錄用戶的PV，UV；

項(xiàng)目狀況：前期嘗試業(yè)務(wù)階段；

特點(diǎn)：
快速實(shí)現(xiàn)（不需要做太重，滿足初期推廣運(yùn)營(yíng)即可）快速投入市場(chǎng)去運(yùn)營(yíng)
收集用戶的原始數(shù)據(jù)，三要素：
誰(shuí)在什么時(shí)間閱讀哪篇文章
提到PV，UV腦海中首先浮現(xiàn)特點(diǎn)：
需要考慮性能（每個(gè)客戶每打開(kāi)一篇文章進(jìn)行記錄）允許數(shù)據(jù)有較小誤差（少部分?jǐn)?shù)據(jù)丟失）

架構(gòu)設(shè)計(jì)

架構(gòu)圖：

時(shí)序圖

記錄基礎(chǔ)數(shù)據(jù)MySQL表結(jié)構(gòu)

測(cè)試

模擬用戶請(qǐng)求訪問(wèn)后臺(tái)（多次請(qǐng)求）

查看緩存中訪問(wèn)數(shù)據(jù)

模擬定時(shí)任務(wù)將緩存中數(shù)據(jù)同步到DB中

這時(shí)查看緩存中的數(shù)據(jù)已經(jīng)沒(méi)了

查看數(shù)據(jù)庫(kù)表結(jié)構(gòu)

總結(jié)

項(xiàng)目中定時(shí)任務(wù)
問(wèn)演示方便用http代替定時(shí)任務(wù)調(diào)度；實(shí)際項(xiàng)目中用XXL-job,參考:定時(shí)任務(wù)的選型及改造
定時(shí)任務(wù)項(xiàng)目中用redis鎖防止并發(fā)（定時(shí)任務(wù)調(diào)度端多次調(diào)度等)，參考:Redis實(shí)現(xiàn)計(jì)數(shù)器—接口防刷—升級(jí)版（Redis+Lua）
后期運(yùn)營(yíng)數(shù)據(jù)可以從閱讀記錄表中拉數(shù)據(jù)進(jìn)行相關(guān)分析
訪問(wèn)量大：可以將MySQL中的閱讀記錄表定時(shí)遷移走（MySQL建歷史表，MongoDB等）
