What is Kafka's retention policy and how does it work?
Kafka's retention policy determines how long messages are stored in a topic. It can be based on time or size.
Can I configure the retention policy for individual topics?
Yes, you can set different retention policies for each topic in Kafka, allowing for flexibility based on your needs.
What happens when the retention period expires?
When the retention period expires, Kafka will delete the oldest messages to free up space for new ones.
