Re: Go SDK: How are re-starts handled?


The job name is a user chosen value[1]. If you don't specify something, a job name is generated for you automatically[2].

But beam.Run() only returns an error. How do I get the job name back?
My guess is that I have to use a different API (https://godoc.org/google.golang.org/api/dataflow/v1b3). Is that the correct way to detect job name collisions?

Thanks again.
