Andrew Purtell commented on HBASE-7801:
---------------------------------------

bq. In 0.96 this can be handled cleanly via protobufs and 0.94 we can have a 
special mutation attribute.

We still have op attributes in 0.96 too. Could you say more about how it would 
be done differently between 0.94 and 0.96+?
                
> Allow a deferred sync option per Mutation.

> For batch operation we'd take the safest sync option of any of the mutations. 
> I.e. if there is at least one that wants to be flushed we'd sync the batch, 
> if there's none of those but at least one that wants deferred flush we defer 
> flush the batch, etc.
