ActorReceiver

abstract class ActorReceiver extends Actor

:: DeveloperApi :: A base Actor that provides APIs for pushing received data into Spark Streaming for processing.

@DeveloperApi()
Example: 

  1. class MyActor extends ActorReceiver {
    def receive {
        case anything: String => store(anything)
    }
}

AkkaUtils.createStream[String](ssc, Props[MyActor](),"MyActorReceiver")
Note

Since Actor may exist outside the spark framework, It is thus user's responsibility to ensure the type safety, i.e. parametrized type of push block and InputDStream should be same.

  29. def store[T](item: T, timeout: Timeout): Future[Unit]

    Store a single item of received data to Spark's memory and returns a Future.

    Store a single item of received data to Spark's memory and returns a Future. The Future will be completed when the operator finishes, or with an akka.pattern.AskTimeoutException after the given timeout has expired. These single items will be aggregated together into data blocks before being pushed into Spark's memory.

    This method allows the user to control the flow speed using Future

  30. def store[T](item: T): Unit

    Store a single item of received data to Spark's memory asynchronously.

    Store a single item of received data to Spark's memory asynchronously. These single items will be aggregated together into data blocks before being pushed into Spark's memory.

  31. def store(bytes: ByteBuffer): Unit

    Store the bytes of received data as a data block into Spark's memory.

    Store the bytes of received data as a data block into Spark's memory. Note that the data in the ByteBuffer must be serialized using the same serializer that Spark is configured to use.

  32. def store[T](iter: Iterator[T]): Unit

    Store an iterator of received data as a data block into Spark's memory.
