> As the picture shows, in multi-machine room acrtiture , the consumer may be
> deployed in different IDC and so do the broker.
> But the user may possiblly need to consumer message from its own IDC since it
> is near and faster. But when problem occurs say all consumers in one IDC is
> crashed, the messages can also be consumed by other consumers in other IDC.
> This is a very important feature for many users, but currently, if the user
> needs this feature, they must implement their own allocate strategy which is
> not easy and error prone.
> And, this feature should be be conflict to the existing allocate strategy
> that means the user can still choose their better allocate strategy say
> AVERAGE or AVERAGE_BY_CIRCLE, but nearby machine room will be supported
> easily too.
