Course Overview

The 'KSQL on ksqlDB for Stream Processing' course by Open Source is designed to equip data engineers, streaming application developers, and real-time analytics specialists with the skills to build event-driven applications using SQL-based stream processing. This training directly supports preparation for the Confluent Certified Developer for Apache Kafka (CCDAK) exam, a widely recognized credential in the data streaming industry. With over 70% of Fortune 500 companies adopting Apache Kafka for real-time data infrastructure, expertise in ksqlDB is in high demand across financial services, e-commerce, and technology sectors. The course is ideal for professionals seeking to leverage SQL for continuous data transformations without deep Java or Scala coding.

Participants will work extensively with core technologies including Apache Kafka, ksqlDB Server, Confluent Control Center, Kafka Connect, Schema Registry, and the ksqlDB CLI. Through hands-on labs conducted in a Docker-based local environment, students build persistent queries that filter, join, aggregate, and enrich live data streams. A key project involves creating a real-time rider location tracking system by joining GPS event streams and querying materialized views using pull and push queries. Learners configure streams and tables from existing Kafka topics, implement windowed aggregations, and use CSAS (CREATE STREAM AS SELECT) statements to derive new topics—mirroring production workflows used in fraud detection and operational monitoring systems.

This course prepares learners for the Confluent Certified Developer for Apache Kafka (CCDAK) certification, which validates critical skills in stream processing and is recognized by leading employers like Netflix, Uber, and LinkedIn. Certified professionals report average salary increases of 12–15%, with senior roles commanding up to $260,000 annually in the U.S. Koenig Solutions enhances learning with Guaranteed-to-Run batches, official courseware, and 1-on-1 mentoring, ensuring mastery of ksqlDB’s SQL syntax and real-time query execution. Upon completion, graduates are positioned to advance into roles such as Streaming Data Engineer or Real-Time Analytics Architect, driving innovation in event-driven architectures.
