During this instructor-led, hands-on course, you will learn howto use Confluent KSQL to transform, enrich, filter and aggregate streams of real time data using a SQL-like language. You will also learn how to use the Apache Kafka Streams library to build streaming applications. Furthermore, you will learn how to test, monitor, secure and scale those streaming applications. You will learn how these applications integrate with the Confluent Streaming platform powered by Apache Kafka, Kafka Connect, Confluent Schema Registry, Confluent REST Proxy as well as the Confluent Control Center. You will learn the role of Streaming in the modern data distribution pipeline, discuss architectural concepts and components of KSQL and Kafka Streams.

Throughout the course, hands-on exercises reinforce the topics being discussed. Exercises include:

  • Installing KSQL containerized and natively
  • Transforming and aggregating data streams with KSQL
  • Writing Kafka Streams App using DSL and Processor API
  • Testing a Kafka Streams App
  • Monitoring a Kafka Streams App
  • Securing a Kafka Streams App
  • Scaling a Kafka Streams App

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