Weiwei Yang commented on YUNIKORN-462:
--------------------------------------
If we can make them a sync'd call that does all the required updates, that
might work. That is something different than our event handling framework today
in the core-repo. Just keep in mind, the assumePod and forgetPod are needed,
because the actual pod binding/deletion happens way slower than scheduler's
allocation.
> Streamline core to shim update on allocation change

> Key: YUNIKORN-462
> URL: https://issues.apache.org/jira/browse/YUNIKORN-462
> Project: Apache YuniKorn
> Issue Type: Sub-task
> Components: core - scheduler, shim - kubernetes
> Reporter: Wilfred Spiegelenburg
> Assignee: Manikandan R
> Priority: Major
>
> Currently in the scheduler we have two updates that get send to the shim when
> an allocation is added or released:
> * event to shim RM event handler to allocate
> * reconciler plugin to update the shim caches
> Before YUNIKORN-317 one update was made in the cace the other in the
> scheduler. Now they are both in the scheduler in quick succession. The cache
> update in the shim is needed to make sure that the predicates are seeing the
> correct info. The event does the real bind etc of the allocation on the node.
> We should be able to fold the two calls into one call. However this requires
> changes on both sides and might even impact the SI as it will likely become a
> synced event call.
