Hi, There is something called as heartbet consumer thread. This threads running on consumer keeps sending heartbeats at regular interval as per the setting heartbeat.interval.ms. It keeps on telling broker that I am very much alive.
https://docs.confluent.io/platform/current/installation/configuration/consumer-configs.html#consumerconfigs_heartbeat.interval.ms There is another setting session.timeout.ms. If the time duration between 2 heartbeats exceeds the time limit set in this setting then broker removes the client(consumer) from the group. Please read above settings in documentation. I hope you can co-relate this with your problem. Regards, Sunil.
