I've said my take on the solution before... But here again: We generate a list of 6-digit Base30 ids(2 million or so ... ) (..or 8-digit). randomly allocate and make them used. During sync when the ids collide we use the internal uuid to create separate rows and internally we always use a combination id for each row
