Kafka vs. RabbitMQ (Event Streaming vs. Message Queues)
Both pass messages between systems, so 'messaging experience' on a resume could mean either. RabbitMQ (and AWS SQS) is a traditional queue: a message is handed to one worker, processed and gone. Kafka is an event log: huge volumes of events are stored in order, many systems can read them independently, and they can be replayed later. Kafka experience at scale is the rarer and more valuable skill.
How to tell them apart on a resume
Message queue (RabbitMQ, SQS, ActiveMQ)
Background jobs, task queues, retries, dead-letter queues, Celery — sending work to be done later, like emails or report generation.
Event streaming (Kafka, Kinesis, Pulsar)
Topics, partitions, consumer groups, Kafka Streams, Flink, schema registry, millions of events per day — real-time data pipelines and event-driven systems.
The question that settles it
“Were you sending individual tasks to workers, or streaming large volumes of events that several systems read — and roughly how many messages a day?”
