Use AWS SQS in Scala Play 2.4 reactive project

[Tianhao Li]

I want to use AWS SQS in my Play 2.4 project.

There are two options at moment:

1. 1. There is a SQS wrapper called https://github.com/kifi/franz which supports reactive way of using that. But it seems not quite popular on Github not sure how mature it is? Whether the developers will continue to maintain it.

2. 2. There is Java SQS SDK, but it doesn't support Scala Future (reactive way). If I want to make it non-blocking, could I use Akka or?

3. Thanks.

Hi,

Have a look to this piece of code to transform async operation from AWS SDK to a scala future:

import java.util.concurrent.{Future => JuncFuture}

	def futureOf[X <: AmazonWebServiceRequest, T](call: (X,AsyncHandler[X, T]) => JuncFuture[T], req: X): Future[T] = {
	val p = Promise[T]()
	val h = new AsyncHandler[X, T] {
	def onError(exception: Exception) { p.complete(Failure(exception)) }
	def onSuccess(request: X, result: T) { p.complete(Success(result)) }
	}
	call(req, h)
	p.future
	}

Hope this help,

Mariot

Actually it's way easier when AWS SDK returns a java future you could just use:

https://github.com/scala/scala-java8-compat/blob/master/src/main/scala/scala/compat/java8/FutureConverters.scala

import scala-java8-compat and import FutureConverts._

then you could just upgrade via .toScala

Thanks for this. Will evaluate it and compare with the reactive library.
