Yu Li commented on HBASE-16505:
-------------------------------

>From the codes, client won't affect the server behavior, but 
>{{RegionOperationContext}} makes client possible to get the result in an 
>asynchronous non-blocking way. We cannot "keep the duration of t3-t2 small" 
>since it's decided by client behavior but the lock won't be kept for t3-t2, it 
>will get released just as before.

[~yangzhe1991] please correct me if I stated anything wrong.

> Add AsyncRegion interface to pass deadline and support async operations

> If we want to know the correct setting of timeout in read/write path, we need 
> add a new parameter in operation-methods of Region.
