Akka Streams 1.0 and Slick 3.0

Reactive Streams 1.0.0 is now live, and so are our implementations in Akka Streams 1.0 and Slick 3.0. 

Reactive Streams is an engineering collaboration between heavy hitters in the area of streaming data on the JVM. With the Reactive Streams Special Interest Group, we set out to standardize a common ground for achieving statically-typed, high-performance, low latency, asynchronous streams of data with built-in non-blocking back pressure—with the goal of creating a vibrant ecosystem of interoperating implementations, and with a vision of one day making it into a future version of Java.

Akka (recent winner of “Most Innovative Open Source Tech in 2015”) is a toolkit for building message-driven applications. With Akka Streams 1.0, Akka has incorporated a graphical DSL for composing data streams, an execution model that decouples the stream’s staged computation—it’s “blueprint”—from its execution (allowing for actor-based, single-threaded and fully distributed  and clustered execution), type safe stream composition, an implementation of the Reactive Streaming specification that enables back-pressure, and more than 20 predefined stream “processing stages”  that provide common streaming transformations that developers can tap into (for splitting streams, transforming streams, merging streams, and more).

Slick‚Äč is a relational database query and access library for Scala that enables loose-coupling, minimal configuration requirements and abstraction of the complexities of connecting with relational databases. With Slick 3.0, Slick now supports the Reactive Streams API for providing asynchronous stream processing with non-blocking back-pressure. Slick 3.0 also allows elegant mapping across multiple data types, static verification and type inference for embedded SQL statements, compile-time error discovery, and JDBC support for interoperability with all existing drivers.

Join Akka software engineer Endre Varga and Slick tech lead Stefan Zeiger to learn how Akka Streams 1.0 and Slick 3.0 are leveraging Reactive Streams to ease development of Reactive applications.

Endre has been a teacher and PhD student at the Technical University of Budapest, where he has been researching complex systems and mobile networks. His interest in distributed, high-performance and concurrent systems lead him to the world of actors and Akka in 2012. Currently, he is one of the core contributors of the Akka Stream subproject.

Stefan Zeiger
Slick Tech Lead
Typesafe, Inc.

Stefan Zeiger is the tech lead for Slick. He joined Typesafe in 2011 after developing ScalaQuery, the predecessor to Slick, in order to work on the new project full-time. He has been a user of Java and the JVM platform professionally since 1996, working on a diverse range of projects from web servers to GUI frameworks and programming language design, and moving on from Java to Scala since 2008.
