> 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.
