ZIO SQS

ZIO SQS is a ZIO-powered client for AWS SQS. It is built on top of the AWS SDK for Java 2.0 via the automatically generated wrappers from zio-aws.

Introduction

ZIO SQS enables us to produce and consume elements to/from the Amazon SQS service. It is integrated with ZIO Streams, so we can produce and consume elements in a streaming fashion, element by element or micro-batching.

Installation

In order to use this library, we need to add the following line in our build.sbt file:

libraryDependencies += "dev.zio" %% "zio-sqs" % "0.6.3"

Example

In this example we produce a stream of events to the MyQueue and then consume them from that queue:

import zio._
import zio.aws.core.config.AwsConfig
import zio.aws.netty.NettyHttpClient
import zio.aws.sqs.Sqs
import zio.sqs.producer.{Producer, ProducerEvent}
import zio.sqs.serialization.Serializer
import zio.sqs.{SqsStream, SqsStreamSettings, Utils}
import zio.stream.ZStream

object ProducerConsumerExample extends ZIOAppDefault {
  val queueName = "MyQueue"

  val stream: ZStream[Any, Nothing, ProducerEvent[String]] =
    ZStream.iterate(0)(_ + 1).map(_.toString).map(ProducerEvent(_))

  val program: ZIO[Sqs, Throwable, Unit] = for {
    _        <- Utils.createQueue(queueName)
    queueUrl <- Utils.getQueueUrl(queueName)
    producer  = Producer.make(queueUrl, Serializer.serializeString)
    _        <- ZIO.scoped(producer.flatMap(_.sendStream(stream).runDrain))
    _        <- SqsStream(
                  queueUrl,
                  SqsStreamSettings(stopWhenQueueEmpty = true, waitTimeSeconds = Some(3))
                ).foreach(msg => Console.printLine(msg.body))
  } yield ()

  def run =
    program.provide(
      Sqs.live,
      AwsConfig.default,
      NettyHttpClient.default
    )
}
