> Key: MESOS-9608
> URL: https://issues.apache.org/jira/browse/MESOS-9608
> Project: Mesos
> Issue Type: Improvement
> Reporter: Meng Zhu
> Priority: Major
> Labels: resource-management
>
> Currently, the `ResourceQuantity` only provides a minimal map interface with
> no built-in arithmetic and contains operations. This makes it unwieldy.
> The intention was to avoid the ambiguities between "absent-means-zero"
> (guarantee like semantic) and "absent-means-infinite" (limits like semantic).
> Instead of only providing a minimal interface and leave the rest to the
> caller, we should provide two classes for each semantic:
> - "ResourceQuantities" will have "absent-means-zero" semantic
> - "ResourceLimits" will have "absent-means-infinite" semantic
> We can have both classes derived from the current class (rename to
> "ResourceMap") to save some common logic.
