This single cluster in the following section can mirror any number of source clusters.The main design elementsKafka is different from most other information systems because of a few of the more important design decisions:

KAFKA[1] is a distributed message queue used by LinkedIn for log processing, and the log data of LinkedIn is large, but the reliability requirements are not high, and its log data mainly includes user behavior (login, browse, click, Share, like) and system run log (CPU, memory, disk, network, System and process status).Many of the current Message Queuing services provide reliable delivery guarantees, and the default is instant consumption (not suitabl
