> But the Table#append and #increment can handle the null result...that is an inconsistent
behavior for user.
> I have noticed two scenarios that server will return null result to user.
> # postAppend/postIncrement return null
> # mutation.isReturnResults() is false and preIncrementAfterRowLock/preAppendAfterRowLock
doesn't return null
> We should wrap the null to empty result on server side. CP user should throw Exception
rather than return null if they intend to say something is broken.
