> The built-in allocator performs "coarse-grained" allocation, meaning that it always allocates
the entire remaining agent resources to a single framework. This may heavily impact allocation
fairness in some cases, for example in presence of numerous greedy frameworks and a small
number of powerful agents.
> A possible solution would be to allow operators explicitly specify granularity via allocator
flags. While this can be tricky for non-standard resources, it's pretty straightforward for
{{cpus}} and {{mem}}.
