How do I use jobId when creating job

[wernermorgenstern]

So I have a question. When creating a job (queue.add(...)) there is an optional parameter for jobId.

What is the recommended option for each type of job?

1. We have repeatable jobs (using every: for example every 10 seconds), or using patterns (cron patterns). The queue, and adding the job, and the worker are configured in one microservice.
2. Then we have "nomal" jobs. For example, one microservice gets data from a MQTT Broker, then processes the data, and creates job (one time job), and then another microservice has the worker configured for that queue, and that Microservice will process that data.

As far as I have read, for repeatable jobs, the jobId can be specific to make it unique. However, when I restart the service, I don't want to create another repeatable job (because jobId is ulid() - a uuid).

I am a bit confused on the jobId option.
Is there a way to get some clarification around that please?
