How exactly did you design the Kafka integration?

When designing Kafka integration, I usually start by defining business requirements: what data and events need to be transmitted, with what frequency and delivery guarantees. Then I choose an appropriate architecture — for example, a producer-consumer setup using topics to separate data streams.

Main steps:

• Defining topics and message schemas (often using Avro or Protobuf for serialization).
• Configuring producers considering reliability parameters (acks, retries, batch.size).
• Configuring consumers with load balancing and offset handling for guaranteed delivery.
• Ensuring monitoring and logging to track the integration status.

Example: if the integration is needed to transmit order events from the order microservice to the analytics service, I create a topic orders-events, the producer sends creation and update events of orders, and the consumer in analytics reads and updates reports.

It is also important to consider error handling and retries to avoid data loss or duplication.
