Hi Flink users, I am trying to use Adaptive Scheduler to auto scale our Flink streaming jobs (NOT batch job). Our jobs are running on YARN with application mode. There isn't much doc around how adaptive scheduler works. So I have some questions:
1. How does Adaptive Scheduler work with YARN/Application mode? If the scheduler decides to request more tasks will it trigger the request to YARN while the job is already running 2. What's the evaluation criteria to trigger a scale-up ? Is it possible to manually trigger a scale-up for testing purposes? Thanks
