Hi all,
I have a basic question regarding kafka consumer groups. I will detail it with an example : 1.I run a console-producer on a topic and produce messages : kafka-console-producer.sh --broker-list localhost:9092 --topic first_topic >message1 >message2 2.I run console-consumer with —group first_group without —from-beginning kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic first_topic --group first_group (no messages come) 3. when I described first_group using kafka-consumer-group , I see the current offset is 2 Now I run console-consumer with —group second_group with —from-beginning I see the messages : kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic first_topic —group second_group —from-beginning message1 message2 My question here is , how with the first_group , based on --from-beginning flag , current offset is set to 2 without actually reading any messages? Please let me know If I am missing something basic here. Thanks in advance. Regards, Sharmadha S.
