bq. Or just restart replication after the slave is back online and interleave
edits from the queue with new ones as necessary?
[...] this could cause application problems if they need to assume a single
arrow of time of edits, and not wanting to see a partial world view

Ok, makes sense for the first cut. Especially if replication logic is pluggable
and subclassable. Applications can plug in their own policies to do what makes
the most sense for them.

>
> We need a nice way of handling long network partitions without impacting a
> master cluster (which pushes the data). Currently it will just retry over and
> over again.
> I think we could:
> - Stop replication to a slave cluster if it didn't respond for more than 10
> minutes
> - Keep track of the duration of the partition
> - When the slave cluster comes back, initiate a MR job like HBASE-2221
> Maybe we want less than 10 minutes, maybe we want this to be all automatic or
> just the first 2 parts. Discuss.
