自動化日誌處理架構

主要講這家公司怎麼串接一堆 google cloud service 來打造一個 logger 加值應用服務，前因後果：
該公司一部份本業在開發 hybrid app，他們有一套 app 更新日誌的機制放在 google cloud，所以串了一個

bucket -> (定時生)access log -> (pub/sub) -> app engine -> data flow -> big query / visualization / etc 的流程，

主要強調這不僅讓他的 RD 練功，業務有武器去打仗，也讓客戶相信他們是熟悉 GCP 的公司，
雖然 ... speaker demo 的 POC 和架構在後面第三場 session 被 Google speaker 吐槽到不行...

To intercept and modify the response, browser could render with your mutation
(function () {
const XHR = window.XMLHttpRequest;
function newXHR () {
var xhr = new XHR();
xhr.addEventListener("readystatechange", () => {
if (xhr.readyState === 4) {
var originalResponse = JSON.parse(xhr.responseText); // store first
Object.defineProperty(xhr, "responseText", { writable: true }); // make it writable, careful it will also clear it
