Implementing Dynamic Sampling in a Spark Streaming Application

Hi all, Spark has had a backpressure implementation since 1.5 that helps to stabilize a Spark Streaming application in terms of keeping the processing time/batch under control and less than the batch interval. This implementation leaves excess records in the source (Kafka, Flume etc) and they get
