Hi Jun,
Please ignore the earlier mail.
I have a Kafka Cluster running on AWS machines i.e. 3 Zookeeper and 2
Brokers. I am trying to scale the brokers while producing and consuming
messages.
I am sending 1000 messages by batch producer every second for 200 seconds
for the following topics:
topics : Topic1(20 partitions) Topic2(40 partitions)
Replication Factor.
Add 1 broker:
Produced Consumed
Topic1 200000 199950
Topic2 200000 199975
Remove 1 broker:
Produced Consumed
Topic1 200000 199950
Topic2 200000 199825
I run a script which reassigns the partitions. And as it can be seen from
the above numbers that we see data loss at the consumer end.
Let me know if you need any further details.
Regards,
Vinayak
