Hello In flink 1.5 release notes - https://flink.apache.org/news/2018/05/25/release-1.5.0.html#release-notes
Various Other Features and Improvements: Applications can be rescaled without manually triggering a savepoint. Under the hood, Flink will still take a savepoint, stop the application, and rescale it to the new parallelism. What exactly does this statement mean? How to rescale the application ? If i'm running my flink job application with parallelism of 5 and then I execute the following command flink run <jar_path> -p 10 then will the application rescale to 10 parallelism? Adding on what will be the behavior in flink 1.5 if I increase the number of task manager in a flink cluster? So if i have a flink job running on flink cluster having 1 task manager and i increase the number of task manager to 2 will the flink rescale the flink job also or will the flink job be unaffected?
