> Priority: Critical
>
> It could be useful to support admission controller min and max memory clamp
> settings for dedicated coordinator memory estimates. This will help with edge
> cases where planner's memory estimation for coordinator could be
> underestimated/overestimated. This would be similar to memory limits that we
> have today for executors:

> impala.admission-control.max-query-mem-limit.<resource_pool>
> {code}
