Master the Confluent Certified Developer for Apache Kafka (CCDAK) exam — building event-streaming applications on Apache Kafka: designing topics, partitions, and keys for ordering and parallelism; tuning producers with acks, idempotence, batching, and compression; managing consumer groups, rebalances, offsets, and commit semantics; choosing at-least-once, idempotent, and transactional exactly-once delivery; serializing with Avro, Protobuf, and JSON Schema and evolving schemas through Schema Registry compatibility modes; processing streams with Kafka Streams (KStream, KTable, GlobalKTable, windows, and joins); moving data with Kafka Connect source and sink connectors, converters, and SMTs; testing with the TopologyTestDriver; and observing client metrics and consumer lag.
$79 practice exams are gatekeeping. Mine are $9 because it should be. Written by someone who works in cloud and AI at Microsoft NZ — for people like us.
I just passed with a 777 (Yes, Seriously). This video helped me tremendously.
