> For colocated partition regions with parallel wan queue, rebalance could
> cause primary to be moved. This can lead to a case that one server has the
> primary bucket for the parent region, but another has the primary bucket for
> the child region. As colocated regions show the same parallel wan queue, both
> server will generate next tail key for different events. This will cause some
> event not dispatched to the other wan site and thus event lost.
