------------------------------------
[~weichiu],[~sodonnell],[~linyiqun] do you have time to review this solution?
It works well in our internal cluster. I believe this is useful feature if we
can push it forward.
Any suggestions and comments are welcome. We will prepare new patch based on
trunk if come to an agreement on this solution.
