Learn Apache Kafka® from Confluent, the company founded by Kafka's original developers.

Confluent Stream Processing Using Apache Kafka® Streams and KSQL

Course Objectives

During this instructor-led, hands-on course, you will learn to:

  • Identify common patterns and use cases for real-time stream processing
  • Understand the high level architecture of Kafka Streams
  • Write real-time applications with the Kafka Streams API to filter, transform, enrich, aggregate, and join data streams
  • Describe how KSQL combines the elastic, fault-tolerant, high-performance stream processing capabilities of Kafka Streams with the simplicity of a SQL-like syntax
  • Author KSQL queries that showcase its balance of power and simplicity
  • Test, secure, deploy, and monitor Kafka Streams applications and KSQL queries

Who Should Attend?

This course is designed for application developers, architects, DevOps engineers, and data scientists who need to interact with Kafka clusters to create real-time applications to filter, transform, enrich, aggregate, and join data streams to discover anomalies, analyze behavior, or monitor complex systems.

Course Prerequisites

Attendees should be familiar with developing professional apps in Java (preferred), .NET, C#, Python, or other major programming language. Participants are required to provide a laptop computer with unobstructed internet access to fully participate in the class.

Additionally, students require a strong knowledge of the Apache Kafka architecture as well as knowledge of Kafka client application development, either through prior experience or by taking the recommended prerequisites, Confluent Fundamentals of Apache Kafka® and Confluent Developer Skills for Building Apache Kafka®.
