Niklas Quarfot Nielsen commented on MESOS-2735:
-----------------------------------------------
Can you capture some of the recent discussions here? I wanted to understand how
providing a callback to update the most recent value was different from having
a callback hanging off the future on the estimator::update()
> Change the interaction between the slave and the resource estimator from
> polling to pushing

> This will make the semantics more clear. The resource estimator can control
> the speed of sending resources estimation to the slave.
> To avoid cyclic dependency, slave will register a callback with the resource
> estimator and the resource estimator will simply invoke that callback when
> there's a new estimation ready. The callback will be a defer to the slave's
> main event queue.
