Hello,
I'd like to know the number of connections that Kafka clients establish. I mean ... The producer establishes a TCP connection for each "leader" broker which has the partition where the producer itself wants to send messages. Is there any other connection to consider ? The consumer establishes a TCP connection for each "leader" broker which has the assigned partition (or requested by client itself) for reading. Other than that I understood that consumer has a TCP connection even with the coordinator for polling information about group changes and partitions will be re-balanced. Is there any other connection to consider ?
