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.

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?
