Does Kafka store data?

The answer is no, there's nothing crazy about storing data in Kafka: it works well for this because it was designed to do it. Data in Kafka is persisted to disk, checksummed, and replicated for fault tolerance. Accumulating more stored data doesn't make it slower.

The offset is a simple integer number that is used by Kafka to maintain the current position of a consumer. That's it. The current offset is a pointer to the last record that Kafka has already sent to a consumer in the most recent poll.

How does Kafka consumer group work?

Consumer Group. Kafka assigns the partitions of a topic to the consumer in a group, so that each partition is consumed by exactly one consumer in the group. Kafka guarantees that a message is only ever read by a single consumer in the group. Consumers can see the message in the order they were stored in the log.
