             Summary: Set Streaming MaxRate Independently For Multiple Streams
                 Key: SPARK-17510
                 URL: https://issues.apache.org/jira/browse/SPARK-17510
             Project: Spark
          Issue Type: Improvement
          Components: Streaming
    Affects Versions: 2.0.0
            Reporter: Jeff Nadler


We use multiple DStreams coming from different Kafka topics in a Streaming application.

Some settings like maxrate and backpressure enabled/disabled would be better passed as config
to KafkaUtils.createStream and KafkaUtils.createDirectStream, instead of setting them in SparkConf.

Being able to set a different maxrate for different streams is an important requirement for
us; we currently work-around the problem by using one receiver-based stream and one direct
stream.   

We would like to be able to turn on backpressure for only one of the streams as well.
