storm

Type Members

1. abstract class BaseBolt extends IRichBolt

2. class CollectorMergeableStore[K, V] extends MergeableStore[(K, Tuple, BatchID), V]

   CollectorMergeableStore merges (K, BatchID) -> V into the underlying store by way of a storm topology.

3. sealed trait FMItem extends AnyRef

   Object containing helper functions to build up the list of storm operations that can potentially be optimized.

4. case class FactoryCell(factory: StoreFactory[_, _]) extends FMItem with Product with Serializable

5. class FinalFlatMapBolt[Event, Key, Value] extends BaseBolt

6. case class FlatMap(op: FlatMapOperation[_, _]) extends FMItem with Product with Serializable

7. trait FlatMapOperation[-T, +U] extends Serializable with Closeable

8. class FunctionFlatMapOperation[T, U] extends FlatMapOperation[T, U]

9. case class FutureQueue[T](init: Future[T], maxLength: Int) extends Product with Serializable

   Maintains a rolling window of futures.

10. class IntermediateFlatMapBolt[T] extends BaseBolt

    This bolt is used for intermediate flatMapping before a grouping.

11. class LocalStorm extends Storm

12. case class MergeableStoreSupplier[K, V](store: () ⇒ MergeableStore[(K, BatchID), V], batcher: Batcher) extends StormStore[K, V] with Product with Serializable

13. trait OnlineSink[-Event] extends (Event) ⇒ Future[Unit]

    Represents a location to which intermediate results of the "flatMap" operation can be written for consumption by other jobs.

14. case class OptionMap[T, U](op: (T) ⇒ Option[U]) extends FMItem with Product with Serializable

15. class RemoteStorm extends Storm

16. class SinkBolt[Key, Value] extends BaseBolt

    The SinkBolt takes two related options: CacheSize and MaxWaitingFutures.

17. type StoreFactory[K, V] = () ⇒ ReadableStore[K, V]

18. case class StoreWrapper[K, V](store: () ⇒ ReadableStore[K, V]) extends StormService[K, V] with Product with Serializable

19. abstract class Storm extends Platform[Storm]

20. case class StormMetric[T <: IMetric](metric: T, name: String, interval: Duration) extends Product with Serializable

    Necessary info for registering a metric in storm "interval" is period over which the metric will be aggregated

21. sealed trait StormService[-K, +V] extends AnyRef

22. sealed trait StormStore[-K, V] extends AnyRef

23. class SummingbirdKryoFactory extends ScalaKryoFactory

24. class WriteOperation[T] extends FlatMapOperation[T, T]
