google-cloud-platform - Pub/Sub vs Http in Cloud Functions Cron Jobs

Question

I want to make Cron Jobs by using Cloud Functions and Google Scheduler I know roughly what Publish / Subscribe is, I searched it. But I still don`t get it perfectly even I read it and over again.

there you have to choose one of three kinds (when you set Google Scheduler) 1. Pub / Sub 2. App engine http 3. Http (just)

Which one of these three should I choose?

I want to delete or set or update the some user`s information data set stored in Firestore in my Android app every night at 12 pm every night.

Answer 1

我假设如下： 1. 您使用 Cloud Function 更新数据 2. 您正在寻找在 GCP 中运行的调度程序解决方案

基于这些假设，您可以参考 Google 的这篇文章：https ://cloud.google.com/scheduler/docs/start-and-stop-compute-engine-instances-on-a-schedule ，调用流程将是：Cloud Scheduler -> Cloud Pub/Sub -> Cloud Function -> Cloud Firestore

还提到了为什么选择 Cloud Pub/Sub 而不是 HTTP(S)，出于安全考虑，也建议您使用 Cloud Pub/Sub，但如果此处不需要身份验证，您应该自行决定

希望能帮助到你
