Ksolves India Limited commented on KAFKA-13453: ----------------------------------------------- HI [~shershai] When a message is published to a Kafka topic, the Kafka client (producer) establishes a TCP connection to the Kafka broker using the bootstrap server's address and port (typically port 9092). *What is the source port in this TCP connection?* The source port is assigned dynamically by the operating system of the machine running the Kafka client. This port is typically chosen from the ephemeral (temporary) port range, which is a range of ports reserved by the OS for short-lived connections. If this satisfies your question you can close this ticket > Query: Kafka source port for publishing messages > ------------------------------------------------ > > Key: KAFKA-13453 > URL: https://issues.apache.org/jira/browse/KAFKA-13453 > Project: Kafka > Issue Type: Task > Components: producer > Reporter: Sheriff > Priority: Major > > When message is getting published to kafka topic, bootstrapserver address and > port is required.
