Producers send data into Kafka, which works as a distributed system for reliability and scale, with logs, which are the basis for storage. Once data is inside the Kafka ecosystem, consumers can help users utilize that data in their other applications and use cases.
Our brokers make up the cluster and coordinate with a ZooKeeper cluster to maintain metadata.
Because Kafka stores data on disk, the ability to replay data in case of an application failure is also part of Kafka’s features set.
