Spring?Boot實戰(zhàn)解決高并發(fā)數(shù)據(jù)入庫之?Redis?緩存+MySQL?批量入庫問題
前言
最近在做閱讀類的業(yè)務(wù),需要記錄用戶的PV,UV;
項目狀況:前期嘗試業(yè)務(wù)階段;
特點:
快速實現(xiàn)(不需要做太重,滿足初期推廣運營即可)快速投入市場去運營收集用戶的原始數(shù)據(jù),三要素:
誰在什么時間閱讀哪篇文章提到PV,UV腦海中首先浮現(xiàn)特點:
需要考慮性能(每個客戶每打開一篇文章進(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
架構(gòu)圖:

時序圖

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

模擬用戶請求訪問后臺(多次請求)

查看緩存中訪問數(shù)據(jù)

模擬定時任務(wù)將緩存中數(shù)據(jù)同步到DB中

這時查看緩存中的數(shù)據(jù)已經(jīng)沒了

查看數(shù)據(jù)庫表結(jié)構(gòu)

總結(jié)
- 項目中定時任務(wù)
- 問演示方便用http代替定時任務(wù)調(diào)度;實際項目中用XXL-job,參考:定時任務(wù)的選型及改造
- 定時任務(wù)項目中用redis鎖防止并發(fā)(定時任務(wù)調(diào)度端多次調(diào)度等),參考:Redis實現(xiàn)計數(shù)器—接口防刷—升級版(Redis+Lua)
- 后期運營數(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
- 訪問量大:可以將MySQL中的閱讀記錄表定時遷移走(MySQL建歷史表,MongoDB等)
