Subject Re: [Hangout] Design and Code review - Kubernetes Host Registration
Date Fri, 26 Sep 2014 09:43:13 GMT
+1 for Raj's suggestion.

Also, how about in "updateX" operations if the updated object is returned
instead of the boolean? That will make the programming in client side easy,
otherwise it will need to do another "getX" call to retrieve the updated
object ?

Thanks,
Sajith
