How have you worked with Kafka in requirements analysis and writing?

When working with Kafka in the context of analysis and requirements writing, I focused on the following aspects:

• Defining business requirements for message exchange: what data, how often, and in what format should be transmitted.
• Analyzing use cases: streaming data, events, integration with other systems.
• Identifying key topics and their structures (keys, values, schemas).
• Requirements for reliability and latency: delivery guarantees, message order.
• Security and access control to topics.

For example, for a monitoring system, I described requirements for topics with metrics, their update frequency, and volume to ensure scalability and system resilience.
