-----------------------------------

Hi [~kkaranasos]

Thanks for the pointers. We want to leverage this feature to improve the 
utilization and throughput of our clusters. So yes, I would like to work on 
some of them and probably some other folks in my team as well. I have just 
tried this feature with trunk image (BTW nice doc!), and will try in some more 
complex cases.

bq. We will upload a design document, summarizing the whole effort

If there is such document available, please share in the jira so I can check 
how many things need to be done before getting this to production.

Thanks a lot.
