Flink backpressure ratio
WebBy default, the job manager triggers 100 stack traces every 50ms for each task in order to determine back pressure. The ratio you see in the web interface tells you how many of these stack traces were stuck in the internal method call, e.g. 0.01 indicates that only 1 in 100 was stuck in that method.
