Benjamin Hindman commented on MESOS-2735:
-----------------------------------------
I'd also like to understand better why to go push instead of pull (poll). One
of the advantages that we had discussed in the past was that the pull model
enables us to move as fast as we possibly can, rather than just getting a bunch
of messages queued up in the slave that we have to process. Even if we want to
collect more fine-grained resource estimations a ResourceEstimator could do
this and store this information until future polls.
> 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.
