Abstract:

A system for managing communication ports in a Kafka cluster is disclosed. The disclosed system receives a maintenance signal to shut down the Kafka cluster for maintenance. The Kafka cluster comprises a plurality of Kafka servers communicating with each other via a plurality of internal communication ports. In response to receiving the maintenance signal, the system shuts off a plurality of external communication ports arranged between the Kafka cluster and a plurality of external servers. Then, the system synchronizes the Kafka servers by replicating data among the Kafka servers. After determining that the Kafka servers are synchronized, the system shuts down the Kafka servers for maintenance. The internal communication ports are retained open when the system shuts down the external communication ports and during the maintenance.
