Jun Rao commented on KAFKA-1507:
--------------------------------
Both the produce and the consumer client will issue TopicMetadataRequest.
Topics should probably be only auto-created by the writers, not the readers,
i.e., it makes sense for topics to be auto-created by the producers, but not by
the consumer or offset reader.
One way to do that is to add a field in TopicMetadataRequest to indicate wether
topic should be auto-created or not. This will be a wire protocol change
though. So, we will have to support both versions on the broker.
> Using GetOffsetShell against non-existent topic creates the topic
> unintentionally
