云功能运行多少个进程? [英] On how many process do cloud function run?

问题描述

我想使用Google云功能来更新位于heroku上的其他数据库，因为firebase realtime database不会删除它.

I would like to use google cloud functions to update an additional database living on heroku because firebase realtime database is not cutting it.

但是heroku接受并发连接的限制，所以我想知道将通过云功能打开多少个并发连接?是1吗?没有限制吗?

However there is a limit of concurrent connections that are accepted on heroku, so I'm wondering how many of them will be opened via cloud functions ? Is it 1 ? Is there no limit ?

我的函数中有类似的东西

I've something like this in my functions

import { Pool } from 'pg';
const pool = new Pool(connectionString);
exports.onAuth = functions.auth.user().onCreate(event => {
  pool.query(...)
});

推荐答案

Cloud Functions将旋转所需数量的服务器实例，以满足您对功能的需求.如果没有负载，它可能低至0，而如果有很多负载，则可能高得多.每个实例都可以为您的功能工作.您不能限制函数实例的数量-它只是根据需要自动缩放.因此，您可以认为它没有限制(只要您支付账单).

Cloud Functions will spin up as many server instances as is required to meet the demand on your functions. It could be as low as 0 if there is no load, and much higher if there is a lot of load. Each instance could be doing work for your function. You can't constrain the number of instances for your functions - it just scales automatically on demand. So you can think of it as having no limit (as long as you are paying your bills).
