node.js - Heroku best practice clocks with node.js

Question

I'm wondering what the best way is to setup a clock process on Heroku. My app is built entirely in Node and I was planning on using node-schedule to specify my schedules.

My question is: should the clock process itself trigger the events in my cron process and run them within it's own allocated dyno? Heroku seems to indicate that you should use a worker to handle this. In that case, I'm wondering how I can get my clock process to tell the worker to run a specific procedure?

I've been reading up on the Python method to do this and it seems like they are simply triggering the process within the same dyno.

Thanks.

Heroku 说时钟进程应该触发一个新的测功机，这对于可扩展性是有意义的，因为你可以将频率提高到 11 并中断时钟进程。https://devcenter.heroku.com/articles/scheduled-jobs-custom-clock-processes

我会使用https://github.com/toots/node-heroku在单独的一次性 dynos 中启动新进程。但是，如果您想拥有一个处理时钟进程的工作人员池，那么您将需要一个像 Resque 或 Kue 这样的队列。时钟进程将新任务加入队列，工作进程将它们出列。
