Type Members

1. case class AnchorTuples(anchor: Boolean) extends Serializable with Product with Serializable

   If true, the topology will anchor tuples in all flatMap bolts and ack in the final sink bolt.

2. case class CacheSize(lowerBound: Int, fuzz: Double = 0.2) extends Serializable with Product with Serializable

   Accepts a lower bound and a percentage of fuzz.

3. case class FlatMapParallelism(parHint: Int) extends Product with Serializable

4. class FlatMapStormMetrics extends AnyRef

5. case class IncludeSuccessHandler(get: Boolean) extends Product with Serializable

   Kryo serialization problems have been observed with using OnlineSuccessHandler.

6. case class MaxWaitingFutures(get: Int) extends Product with Serializable

   MaxWaitingFutures is the maximum number of key-value pairs that the SinkBolt in Storm will process before starting to force the futures.

7. case class OnlineExceptionHandler(handlerFn: PartialFunction[Throwable, Unit]) extends Product with Serializable

8. case class OnlineSuccessHandler(handlerFn: (Unit) ⇒ Unit) extends Product with Serializable

9. case class SinkParallelism(parHint: Int) extends Product with Serializable

   SinkParallelism controls the number of executors storm allocates to the groupAndSum bolts.

10. class SinkStormMetrics extends AnyRef

11. case class SpoutParallelism(parHint: Int) extends Product with Serializable

    Options used by the flatMapping stage of a storm topology.
