Description

The new volume in the Apache Kafka Series!
Learn the Kafka Streams data processing library, for Apache Kafka. Join hundreds of knowledge savvy students into learning one of the most promising data processing library on Apache Kafka.
Kafka Streams
is the easiest way to write your applications on top of Kafka:
> Easiest way to transform your data using the High Level DSL
> Exactly Once semantics support out of the box!
> Deploy and Scale your Kafka Streams application without a cluster!
> Perform Aggregations, joins, and any operations you may think of using only a few lines of code!
> Built on top of Kafka, for fault tolerance, scalability and resiliency
Hands On & Theory Based Course
Note: This course is based on Java 8, and will include one example in Scala. Kafka Streams is Java based, and therefore is not suited for any other programming language. 
Each section can be either theoretical, or a practice section. 
> Through
practice
, you will be challenged by writing your own Kafka Streams application. The solutions will be thoroughly explained, and you will learn some tips on how to use Kafka Streams the best way.
> Through
theory
, you will learn about all the available API, the inner workings of the library, as well as some exciting concepts such as Exactly Once Semantics!
This course is the first and only available Kafka Streams course on the web. Get it now to become a Kafka expert!
Section outline:
Kafka Streams - First Look: 
Let's get Kafka started and run your first Kafka Streams application, WordCount
End-to-End Kafka Streams Application :
 Write the code for the WordCount, bring in the dependencies, build and package your application, and learn how to scale it. This is a complete end to end example
KStream and KTable Simple Operations: 
Learn all the stateless operations available for the KStream and KTable API
Practice Exercise - Favourite Colour: 
Practice your newly acquired skills by writing your own Kafka Streams application, Favourite Colour. It will be challenging! Includes a Scala version of the example
KStream and KTable Advanced Operations: 
Learn all the stateful operations available for the KStream and KTable API
Exactly Once Semantics - Theory:
 Learn what EOS (Exactly Once Semantics) is, how Kafka 0.11 enables it, and how to activate them in Kafka Streams
Exactly Once - Practice Exercise - Bank Balance: 
Practice your newly acquired knowledge by writing your own Kafka Streams Exactly Once application, to compute a running Bank Balance for your customers
Testing your Kafka Streams Application:
 Learn how to test the WordCount Kafka Streams Topology with Kafka Streams v1.1.0
===============================
Instructor
My name is Stephane Maarek, and I'll be your instructor in this course. I teach about Apache Kafka, the Kafka ecosystem and Kafka Certifications with my focus always on helping my students improve their professional proficiencies. I am also the co-founder of Conduktor: an enterprise Apache Kafka platform & UI to help everyone use Kafka.
Throughout my career in designing and delivering these certifications and courses, I have already taught 1,000,000+ students and gotten 350,000+ reviews!
With Apache Kafka becoming much more than a buzzword out there, I've decided it's time for students to properly learn how to be a Kafka professional. So, let’s kick start the course! You are in good hands!
===============================
This Course Also Comes With:
Lifetime Access to All Future Updates
A responsive instructor in the Q&A Section
Links to interesting articles, and lots of good code to base your next applications onto
Udemy Certificate of Completion Ready for Download
This is the course that could improve your career!
Apache Kafka is a skill in high demand and there are not enough people to fulfill all the open positions. You can boost your income, take on new roles and fun challenges. Many of my students are now the Kafka experts of their companies! You can be the next!
I hope to see you inside the course!
