💡 Hint

Common Mistakes

Using 'compact' instead of 'delete' for cleanup policy.

Setting retention hours too low or too high without reason.

Setting log.cleanup.policy to delete enables automatic deletion. log.retention.hours sets retention time in hours (168 = 7 days).

5fill in blank

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using ZooKeeper port 2181 instead of broker port 9092.

Mismatching topic names.

The topic name is 'my-topic'. The bootstrap server and broker list use 'localhost:9092' for Kafka broker communication.
