Yes, Guangya, it is. I think we can close this duplicated one. Thanks for pointing this out.

> Followup JIRA for MESOS-5425. Currently, resource object exposes the protobuf to store data internally. But its implementation is low-efficient for math calculation, especially for the case of Ranges subtraction. An interim solution proposed https://reviews.apache.org/r/48593/ is converting Ranges to IntervalSet inline to optimize the performance. In long-term, we should consider C++ library based resource object as a permanent solution.
