What is the default size of a Kafka message?

• A. 1 MB
• B. 1 KB
• C. 4 MB
• D. 8 MB

Answer: (A)

Kafka limits the size of a single message using the broker setting that controls the maximum bytes per message. By default this value is 1,000,000 bytes, which is about 1 MB. That means a single record cannot be larger than roughly 1 MB unless you raise this limit. If you need to publish bigger messages, you’ll need to increase this broker setting (and, if needed, the producer’s max.request.size) and be mindful of the impact on memory, network I/O, and throughput.
