Hi ,
In Akka Stream is it possible to create custom windows.
For example
case class Source1(id: Int, data: Int)
case class Source2(id: Int, data: Int)
case class Combined(id: Int, data: (Int,Int))
val source1Iter = for (i <- 1 to 100) yield Source1(i, r.nextInt(11))
val source2Iter = for (i <- 1 to 100) yield Source2(i, r.nextInt(1000))
val source1: Source[Source1, NotUsed] = Source.fromIterator(() =>
source1Iter.iterator)
val source2: Source[Source2, NotUsed] = Source.fromIterator(() =>
source2Iter.iterator)
Required to combine this two streams and create stream window based on
the first tuple value from 10 to next 10 and filter the second tuple
highest value.
val sink = Sink.foreach(println)
val g = RunnableGraph.fromGraph(GraphDSL.create() { implicit builder:
GraphDSL.Builder[NotUsed] =>
import GraphDSL.Implicits._
val zipWith = builder.add(ZipWith[Source1, Source2, Combined]((source:
Source1, source0: Source2) => {
Combined(source.id, (source.data, source0.data))
}))
source1 ~> zipWith.in0
source2 ~> zipWith.in1
zipWith.out ~> sink
// Need to implement the block / window logic
ClosedShape
})
g.run(materializer)
Thanks,
Dheeraj.
