How to start multiple jobs all at once via Chronos REST API?

Question

I can start one job my-task-name on chronos manually via its rest api:

http PUT http://my-chronos/scheduler/job/my-task-name
HTTP/1.1 204 No Content
Connection: keep-alive
Content-Type: application/json
Date: Mon, 28 Nov 2016 09:40:55 GMT
Server: openresty/1.7.10.2

yet I have a list of jobs I want to execute manually and I don't want to fire a PUT request for each one of them. Is it possible to execute a batch of task via one request on chronos? Or do I have start each job with its own request?

Answer 1

There are a couple of ways to handle this depending on what you are trying to accomplish.

1. you can schedule all the job via a CRON. In this way no PUT call is required at all, it is completely based on time.
2. you can use dependent jobs assuming actually want to have control of the kick off (the PUT request) but want that to fire many jobs. The setup would consist of creating a "dummy job" (unless you have a real starting job). Imagine a dummy job of "sleep 1". Then have a number of dependent jobs. When the dummy job is complete the other dependent jobs will queue up.
