--------------------------------
Summary: enable Frameworks level disk IO bandwidth support
Key: MESOS-204
URL: https://issues.apache.org/jira/browse/MESOS-204
Project: Mesos
Issue Type: Brainstorming
Reporter: Qinghe Jin
I am considering to add Frameworks level disk IO bandwidth support to
mesos，which behaves like ionice on the single node，but this time it‘s in
multi-nodes。I believe this kind of disk QoS support will be more user
friendly。My initial idea is to allow user to use an ioprio_set like api to set
the io priority when they commit their job. At the same time, here may need
some tools to display the disk IO usage per node/container on the webui.
I have read the mesos paper carefully and I found that in the comment，it
mentioned that in the future it will support disk and network bandwidth
control。But，in my opinion，disk IO bandwidth is more feasible for it has more
locality，and network bandwidth control may be more difficult for the complexity
of the network environment。But I don't know why is there nobody going to add
this feature。Is it useless？Or not feasible？Or just not interested？
For this feature may need a lot of work，I‘d like to listen to your opinions
before I start to work on it。Anybody who have any questions ,suggestions or
ideas, please tell me and I appreciate it very much，Thanks！
