Kafka Consumer With Scala And Akka Streams By о X X Eranga I’m building sbt based scala project in here. 1. alpakka dependency. first we need to add akka stream kafka dependency to our build.sbt. following is the build.sbt file content. 2. akka consumer. 1. akka streams emerged as a dataflow centric abstraction for the akka actors model. these are high performance library built for the jvm and specially designed for general purpose microservices. whereas as long as kafka streams is concerned, these are client libraries used to process unbounded data.
Akka Streams Kafka 0 11 Akka You can use the akka stream batch combinator to perform the batching. note that it will only aggregate elements into batches if the downstream consumer is slower than the upstream producer. val done = consumer mittablesource(consumersettings, subscriptions.topics("topic1")) .mapasync(1) { msg =>. Run kafkaconsumersubscribeapp.scala program. when you run this program, it waits for messages to arrive in “ text topic ” topic. 2. run kafkaproducerapp.scala program. run kafkaproducerapp.scala program which produces messages into “text topic”. now, you should see the messages that were produced in the console. The major strengths of akka streams are again high scalability and fault tolerance, but in a different way, as we will see in the code. akka streams offers an extremely versatile and concise. Overview. the alpakka project is an open source initiative to implement stream aware and reactive integration pipelines for java and scala. it is built on top of akka streams, and has been designed from the ground up to understand streaming natively and provide a dsl for reactive and stream oriented programming, with built in support for backpressure.

Akka streams is a reactive streams and jdk 9 java.util.concurrent.flow compliant implementation and therefore fully interoperable with other implementations. this repository contains the sources for the alpakka kafka connector. which lets you connect apache kafka to akka streams. it was formerly known as akka streams kafka and even reactive kafka.
