When the consumer is complete processing the exchange, and if the exchange failed, then the consumer is going to reject the message from the RabbitMQ broker. Command Line Arguments. RabbitMQ and Kafka consumers interact and fetch data from a broker differently, with Rabbit consumers acting as a workers pool where each available consumer fetch a message from the head of the queue to process, in Kafka only one consumer (per group) can fetch data from a partition to process.
