Aniruddha commented on BOOKKEEPER-256:
--------------------------------------
@Sijie, the code handles the condition when the message might not have it's
local component in sync with the original message. The RegionManager builds the
message passed on to the persistence manager. While doing this, I believe it
resets the message ID.
> Update remote component sequence IDs only for messages from the source region

> In the current setup, remote components for a message being persisted don't
> give any meaningful information about the number of messages the hub has
> received for that topic from other regions. The provided patch fixes this by
> updating the remote component of the locally persisted message for a region X
> only if the message received by the RegionManager originates from region X.
