We do exactly what you mentioned. However, it's not that simple unfortunately. Our services don't have a predictable performance as traffic varies a lot during the day.
As I've explained above increase source parallelism to 2 was enough to tip over our services and reducing parallelism of the async operator to 2 is not an option. -- Sent from: http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/
