[jira] [Created] (SPARK-18580) Use spark.streaming.backpressure.initialRate in DirectKafkaInputDStream

Oleg Muravskiy created SPARK-18580:
--------------------------------------

             Summary: Use spark.streaming.backpressure.initialRate in DirectKafkaInputDStream
                 Key: SPARK-18580
                 URL: https://issues.apache.org/jira/browse/SPARK-18580
             Project: Spark
          Issue Type: Improvement
          Components: DStreams
    Affects Versions: 2.0.2
            Reporter: Oleg Muravskiy


Currently the `spark.streaming.kafka.maxRatePerPartition` is used as the initial rate when the backpressure is enabled. This is too exhaustive for the application while it still warms up.
This is similar to SPARK-11627, applying the solution provided there to DirectKafkaInputDStream.
