Hi team, We are using beta1. I am going to delete all topics and create them with more partitions. But I don't want to lose any messages.
Assume the consumers are online all the time for the following steps. The consumer's auto.offset.reset is set to largest. 1 stop publishing to the brokers. 2 wait until all N messages on the brokers have been consumed 3 delete all topics. That includes deleting the log files and /brokers/topics/mytopic and /consumers/myusergroup/owners/mytopic and /consumers/myusergroup/offsets/mytopic 4 recreate all the topics with more partitions. 5 start the brokers 6 resume publishing to the brokers When a consumer tries to get the next message from a newly created topic, will the OutOfRange Exception will reset the offset to 0 in this case? Thanks, Libo
