Name: Akka/Apache Pekko Streams with Scala
Price: 95 USD

Plug and play.

If you’re reading this, I probably don’t need to talk to you about the reactive manifesto or the Reactive Streams initiative. The terms are fancy but they lay down powerful principles, which have been proven and sent to production in many many many places. The idea is simple: water tap, pipes, sink, plug all and go. Except we call those data sources, transformers and data sinks.

This course is for the Scala & Akka/Pekko developer who wants to write scalable asynchronous data pipelines quickly, also known as “fast data” or “reactive” systems.

You’ll learn to write fault-tolerant async data pipelines at scale, in as many lines as it takes Java to write “hello world”.

This course is compatible with both Akka and Apache Pekko (the open-source version of Akka).

After this course, you’ll be able to:

Use the principles of the reactive manifesto in your applications
Read, transmit and process data with high performance, at scale, with streaming components
Describe massive streams of any shape and size with the Graph DSL, without needing to care about concurrency
Use backpressure to control the flow of data through your system
Use streams materialization, a difficult concept understood only by the very best
Use graph cycles in your streams to your advantage
Create your own streaming components with as much control as you like
Integrate Akka or Pekko Streams with normal actors
Avoid concurrency pitfalls
Circumvent cyclical streaming deadlocks
Maintain data integrity in the face of disproportional demand or supply

Plus some extra perks:

You’ll have access to the entire code I write on camera (all 2100 lines of it)
You’ll be invited to our private Slack room where I’ll share latest updates, discounts, talks, conferences, and recruitment opportunities
(Soon) you’ll have access to the takeaway slides
(Soon) you’ll be able to download the videos for your offline view

I'm a software engineer and the founder of Rock the JVM. I started the Rock the JVM project out of love for Scala and the technologies it powers - they are all amazing tools and I want to share as much of my experience with them as I can.

As of February 2024, I've taught Java, Scala, Kotlin and related tech (e.g. Cats, ZIO, Spark) to 100000+ students at various levels and I've held live training sessions for some of the best companies in the industry, including Adobe and Apple. I've also taught university students who now work at Google and Facebook (among others), I've held Hour of Code for 7-year-olds and I've taught more than 35000 kids to code.

I have a Master's Degree in Computer Science and I wrote my Bachelor and Master theses on Quantum Computation. Before starting to learn programming, I won medals at international Physics competitions.
