Patrick Te Tau commented on KAFKA-1006:
---------------------------------------

Hi [~guozhang], we are also having trouble with our integration tests. 
I can manually set the offset for new topics but this will break my 
subscription to pre-existing topics. Because have no way of telling whether the 
topic is a new one or an old one, I have no way to switch my strategy.
I have considered storing a list of topics on my client but this solution fails 
when I run multiple clients. 
Any suggestions?

> Consumer currently uses auto.offset.reset = largest by default. If a new 
> topic is created, consumer's topic watcher is fired. The consumer will first 
> finish partition reassignment as part of rebalance and then start consuming 
> from the tail of each partition. Until the partition reassignment is over, 
> the server may have appended new messages to the new topic, consumer won't 
> consume these messages. Thus, multiple batches of messages may be lost when a 
> topic is newly created. 
> The fix is to start consuming from the earliest offset for newly created 
> topics.
