Daryn Sharp commented on YARN-6245:
-----------------------------------
Posted to new YARN-6679 in case you wish to pursue the immutable resources,
although the scheduler really should try to reuse instances when possible.
> Add FinalResource object to reduce overhead of Resource class instancing

> There're lots of Resource object creation in YARN Scheduler, since Resource
> object is backed by protobuf, creation of such objects is expensive and
> becomes bottleneck.
> To address the problem, we can introduce a FinalResource (Is it better to
> call it ImmutableResource?) object, which is not backed by PBImpl. We can use
> this object in frequent invoke paths in the scheduler.
