             Summary: Create event cache for queue and application events
                 Key: YUNIKORN-117
                 URL: https://issues.apache.org/jira/browse/YUNIKORN-117
             Project: Apache YuniKorn
          Issue Type: Sub-task
          Components: core - cache, core - scheduler
            Reporter: Adam Antal
            Assignee: Adam Antal


Create a simple preliminary implementation of the event cache of YUNIKORN-42.

We have the following limited scope for this task:
- implement it as a separate process from the scheduler (similar to {{PartitionManager}})
- only deal with queues and applications (the pods and nodes can be added later)
- only store the apps last visited time from the scheduler
- clean up those objects that haven't been visited in the last 24h

Other cache implementations can be also considered.

As a starting point, channels are a safe choice to have async communication with the scheduler without expecting bigger performance loss.
