Video description

If you want to understand the concept of stream processing, this course is for you. Using Kafka, the course will help you get to grips with real-time stream processing and enable you to apply that knowledge to learn Kafka programming techniques.

This course uses the Kafka Streams library available in Apache Kafka 2.x. All the source code and examples on Apache Kafka 2.3 open-source distribution have been tested. You'll understand and explore Confluent Platform functionalities such as Schema Registry and Avro Serdes using the Confluent Community Version. This course makes extensive use of IntelliJ IDEA and Apache Maven as the preferred development IDE. You'll leverage Log4J2 and JUnit5 for industry-standard log implementation in your application and implementing unit test cases, respectively.

What You Will Learn

  • Learn Apache Kafka fundamentals and Kafka Architecture
  • Understand how to create streams using the Kafka Producer APIs
  • Design, develop, and test real-time stream processing applications using the Kafka Streams library
  • Get well-versed with the Kafka Streams architecture, Streams DSL, and the Processor API
  • Support microservice architecture and implement interactive queries in Kafka Streams
  • Explore serializing and deserializing and work on JSON and AVRO messages

Audience

The Kafka Streams - Real-time Stream Processing course is for software engineers looking to develop a stream processing application using the Kafka Streams library. This course will also help Java programmers who want to learn everything necessary to start implementing real-time streaming applications using Apache Kafka. Data architects and data engineers responsible for designing and building the organization’s data-centric infrastructure will benefit from this course.
