Confluent Certified Developer for Apache Kafka (CCDAK)

This section targets CCDAK, the Confluent Certified Developer for Apache Kafka exam. It focuses on producer and consumer behavior, offsets, delivery guarantees, partitions, rebalancing, and schema-evolution basics. The content emphasizes the decisions the exam is really testing: what preserves ordering, what increases throughput safely, and which configuration changes semantics versus only performance.

Offset: Kafka position marker for a record within a partition, used by consumers to track where they are in the log.

Use the cheat sheet for rapid review of Kafka mental models and configuration rules. Use the FAQ for candidate-fit and study-strategy questions, and use the resources page when you need official certification and Kafka documentation.
