When using core api, there can be only one writer at a given time. so when
the writer issues two writes, the two writes will be in the time order of
when they were written.

However when using thin client, there can be multiple writers. the order of
the writes coming from different writers is determined by their arriving
order in the write proxy, not the time order when they are issued.

It is an ordering concern from write perspective - single writer vs
multiple writers. Once the writes arrive in the log, all the readers will
see exactly same order.
