> For now if a table is not created with SERIAL_REPLICATION_SCOPE and later converted to
SERIAL_REPLICATION_SCOPE , then we may have multiple replication sources which replicate the
different ranges for the same region and update the queue storage concurrently. This will
cause problem if the lower range finish at last since the replication position will be wrong...
> Need to find a way to deal with this.
