Enis Soztutar commented on HBASE-7801:
--------------------------------------

Makes sense. I think it is not a horrible idea to expose the PB's as client 
API's. If we want to have non-java clients (especially third party ones), then 
the java api is not our only client-facing API. Our RPC, and the PB's are 
client facing as well. Also, we might get rid of the client objects -> PB -> 
wire -> PB -> server objects flow, and go with client PB -> wire -> server PB 
-> wal/memstore. 
                
> Allow a deferred sync option per Mutation.

> Won't have time for parent. But a deferred sync option on a per operation 
> basis comes up quite frequently.
> In 0.96 this can be handled cleanly via protobufs and 0.94 we can have a 
> special mutation attribute.
> 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.
