[jira] [Commented] (MESOS-2735) Change the interaction between the slave and the resource estimator from polling to pushing

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()

> 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.
