>
> Coprocessor endpoints may do non-trivial amounts of work, yet quotas do not
> throttle them. We can't generically apply quotas to coprocessors because we
> have no information on what a particular endpoint might do. One thing we
> could do is expose checkQuota to the RegionCoprocessorEnvironment. This way,
> coprocessor authors have the tools to ensure that quotas cover their
> implementations.
> While adding this, we can update AggregationImplementation to call checkQuota
> since those endpoints can be quite expensive.
