Working with Apache Kafka (for Developers)

Course Objectives

This “skills-centric” course is about 50% hands-on lab and 50% lecture, coupling the most current techniques with the soundest industry practices. Throughout the course students will be led through a series of progressively advanced topics, where each topic consists of lecture, group discussion, comprehensive hands-on lab exercises, and lab review.

Working in a hands-on learning environment, students will explore

• Overview of Streaming technologies
• Kafka concepts and architecture
• Programming using Kafka API
• Kafka Streams
• Monitoring Kafka
• Tuning / Troubleshooting Kafka

Need different skills or topics?  If your team requires different topics or tools, additional skills or custom approach, this course may be further adjusted to accommodate.  We offer additional Kafka, big data / data science, Hadoop, Apache tooling, DevOps, database, programming and other related topics that may be blended with this course for a track that best suits your needs. Our team will collaborate with you to understand your needs and will target the course to focus on your specific learning objectives and goals.

Course Prerequisites

This in an Introductory and beyond level course is geared for experienced Java developers seeking to be proficient in Apache Kafka.  Attendees should be experienced developers who are comfortable with Java, and have reasonable experience working with databases. Students should also be able to navigate Linux command line, and who have basic knowledge of Linux editors (such as VI / nano) for editing code.
