What integrations have you implemented and what exactly did you do? (Kafka, REST, RabbitMQ, synchronous/asynchronous)

In projects, I implemented integrations with various systems:

• Kafka: configured producers and consumers for asynchronous event transmission between microservices, ensuring real-time data stream processing.

• REST API: created and consumed REST services for synchronous data exchange, implementing authentication and error handling.

• RabbitMQ: used for asynchronous message exchange with delivery guarantees, setting up queues and message routing.

Example: integration with Kafka for order event processing — the service publishes an order creation event to a topic, and another service processes it asynchronously and updates the status.

Thus, the choice between synchronous (REST) and asynchronous (Kafka, RabbitMQ) integrations depends on response time requirements and data transmission reliability.
