In this three-day, hands-on Developer training course, you will learn how to build an application that can publish data to, and subscribe to data from, an Apache Kafka® cluster. You will learn the role of Kafka in the modern data distribution pipeline, Kafka architectural concepts and components, and review Kafka developer APIs.

Skills Gained

In this hands-on course, you will:

  • Write Producers and Consumers to send data to and read data from Kafka
  • Integrate Kafka with external systems using Kafka Connect
  • Write streaming applications with Kafka Streams & ksqlDB
  • Integrate a Kafka client application with Confluent Cloud

Who Can Benefit

Application developers and architects who want to write applications that interact with Apache Kafka®. The course treats Java as a first-class citizen, but students will derive value even if Java is not their primary programming language. Python, C# and NodeJS clients will also be used.

Prerequisites

Attendees should be familiar with developing professional apps in Java (preferred), C#, or Python. Additionally, a working knowledge of the Apache Kafka architecture is required for this course, either through:

Course Details

Hands-on Training:

The hands-on lab exercises in the course follow the coherent story of building and upgrading a driver location app. This gives a throughline throughout the course where concepts are applied directly to a working application. Exercises are available in Java, C# and Python.

Exercises include:

  • Working with Kafka command line tools
  • Producing driver location data to Kafka and consuming that data in real-time
  • Refactoring the application to use Avro and Schema Registry
  • Creating a Kafka Streams application to do real-time distance aggregation
  • Extracting a table from an external database into Kafka using Kafka Connect
  • Creating a full event streaming application using kslqDB that enriches driver location data with driver profile data
  • Experimenting with semantic partitioning

What does vendor-authorized training mean?

As a vendor-authorized training partner, we offer a curriculum that our partners have vetted. We use the same course materials and facilitate the same labs as our vendor-delivered training. These courses are considered the gold standard and, as such, are priced accordingly.

Is the training too basic, or will you go deep into technology?

It depends on your requirements, your role in your company, and your depth of knowledge. The good news about many of our learning paths, you can start from the fundamentals to highly specialized training.

How up-to-date are your courses and support materials?

We continuously work with our vendors to evaluate and refresh course material to reflect the latest training courses and best practices.

ExitCertified instructors have an average of 27 years of practical IT experience. They have also served as consultants for an average of 15 years. To stay up to date, instructors will at least spend 25 percent of their time learning new emerging technologies and courses.

Do you provide hands-on training and exercises in an actual lab environment?

Lab access is dependent on the vendor and the type of training you sign up for. However, many of our top vendors will provide lab access to students to test and practice. The course description will specify lab access.

Will you customize the training for our company’s specific needs and goals?

We will work with you to identify training needs and areas of growth.  We offer a variety of training methods, such as private group training, on-site of your choice, and virtually. We provide courses and certifications that are aligned with your business goals.

How do I get started with certification?

Getting started on a certification pathway depends on your goals and the vendor you choose to get certified in. Many vendors offer entry-level IT certification to advanced IT certification that can boost your career. To get access to certification vouchers and discounts, please contact Edu_customerexperience@techdata.com

Will I get access to content after I complete a course?

You will get access to the PDF of course books and guides, but access to the recording and slides will depend on the vendor and type of training you receive.

it was good and very informative. Instructure covered everything in detail.

Course trainer was excellent, content was well organized. However, labs should be instructor lead versus on your own. Much time is wasted for newbees in getting acclimated to tool set, AWS environment, navigating and setting up things to complete tasks. This was my third class and I was barely able to finish most of the labs. (The first 2 classes I only finished one lab exercise for the 2 together.)

Great company -- easy to sign up and very organized. Loved my teacher and class overall.

Classromm confortable and enviroment. Instructir knowlegeable of course matarial but need to align to students working in the Canadian Federal Govt. ve US Federal govt.

Some Labs are very good but some steps it ask to update but its already updated, but overall its very good training.
