[jira] [Created] (MESOS-8450) SlaveInfo comparison is unnecessarily expensive

Benno Evers created MESOS-8450:
----------------------------------

             Summary: SlaveInfo comparison is unnecessarily expensive
                 Key: MESOS-8450
                 URL: https://issues.apache.org/jira/browse/MESOS-8450
             Project: Mesos
          Issue Type: Bug
            Reporter: Benno Evers


Currently, the comparison operator of `struct SlaveInfo` is creating two temporary `Resources` objects and two temporary `Attributes` objects. All of these constructors do a bunch of work and allocate memory.

 

Instead of passing around `SlaveInfo` in the master, we should probably use some wrapper that stores the raw message as well as caching the lazily generated `Resources` and `Attributes` objects associated with that `SlaveInfo`.
