yes, that is correct.

Thanks for reply. So do I understand correctly if I say that whenever
you query job status it gets cached for a configurable amount of time
and subsequent queries within that time period will not show any change?

This is expected, the backing data structure is cached for a while so
we never hammer the JobManager with requests.
IIRC this is controlled via "web.refresh-interval", with the default
being 3 seconds.

Hi,
I found an interesting behaviour of the REST API in my automated
system tests using that API where I was getting status of a
purposefully failing job.
If you query job details immediately after job submission,
subsequent queries will return its status as RUNNING for a moment
until Flink’s restart strategies are exhausted. If you don’t and
take a brief moment before your first query of the job status, it
will be reported in a more fine-grained fashion, e.g. RESTARTING
or FAILING.
Has anyone else noticed that behaviour?
Thanks,
Tomasz
