class KinesisSourceGraphStage extends GraphStage[SourceShape[CommittableEvent[ConsumerEvent]]] with LazyLogging

A KinesisSourceGraph will attach to a kinesis stream with the provided configuration and constitute a Source[KinesisEvent, NotUsed]. Usage:

val config = ConfigFactory.load()
val consumerConfig = ConsumerConf(config.getConfig("kinesis"), "some-consumer")
val source = Source.fromGraph(new KinesisSourceGraph(consumerConf, system))

Assuming a configuration file like this:

kinesis {
   application-name = "SampleService"
   some-consumer {
      stream-name = "sample-consumer"
   }
}

See reference.conf for a list of all available config options.
