Exam CCAAK Topic 3 Question 36 Discussion

Actual exam question for Confluent's CCAAK exam
Question #: 36
Topic #: 3
You have a cluster with a topic t1 that already has uncompressed messages. A new Producer starts sending messages to t1 with compression enabled.
Which condition would allow this?

Suggested Answer: A Vote an answer

Kafka allows mixed compression formats within the same topic and even the same partition. Each message batch includes metadata indicating whether and how it is compressed. Therefore, a new producer can send compressed messages to a topic that already contains uncompressed messages, as long as it is configured with a compression codec (e.g., compression.type=gzip, snappy, etc.).
