Regarding Kafka — did you have to design and choose topic names?

Yes, when designing Kafka, it is important to choose topic names correctly so that they reflect the meaning of the transmitted data and are easy to support. Usually, topic names are constructed based on a pattern that includes the domain, event type, and environment, for example:

orders.created.prod
user.activity.dev
payments.completed.test

This approach helps quickly understand the purpose of the topic and facilitates data stream management. When designing, consider:

• Clear and unambiguous name
• Use of separators (dots or hyphens)
• Environment levels (prod, dev, test)
• Compliance with business logic and data structure

This simplifies scaling and maintaining the system in the future.
