> We write the current max sequence id plus one as the new max sequence id so
> if we fail before report RIT to master, when assign next time the open
> sequence number will increase by one.
> But it is possible that we fail before writing the open region marker so
> there will no actual WAL with the sequence id which is the open sequence
> number minus one. This will cause the serial replication to be stuck.
