July 2015 Meetup: Reactive Streams with Lutz Hühnken from Typesafe

This Thursday, Underscore is glad to host another member of the Typesafe team - Lutz Hühnken (https://twitter.com/lutzhuehnken).

Agenda

• 18:00 Gathering and mingling over pizza and beer.

• 18:30 A word from the organizers.

• 18:35 Lutz Hühnken - Reactive Streams.

• Time permitting, Gal Topper will discuss his first steps using Akka Streams in a Kafka -> DB augmentation -> File IO process.

Abstract

Reactive streams (http://www.reactive-streams.org) - is an initiative to provide a standard for asynchronous stream processing with non-blocking back pressure on the JVM. It is a collaborative effort by Twitter, Netflix, Pivotal, Red Hat, Typesafe and others.

In this session, we want to talk about streams in general, the main concepts behind the reactive streams API, and how to handle streams with Akka (http://akka.io/). After an introductory talk we are going to go through some code examples using Akka streams, an implementation of reactive streams on top of the Akka actor library. We will look into interfacing streams and actors, and handling streams with Akka's Flows.

Akka HTTP (formerly Spray) and Slick 3 will also be discussed.
