             Summary: Display a unique id on the REST interface when returning events
                 Key: YUNIKORN-1965
                 URL: https://issues.apache.org/jira/browse/YUNIKORN-1965
             Project: Apache YuniKorn
          Issue Type: Sub-task
          Components: core - scheduler
            Reporter: Peter Bacsko
            Assignee: Peter Bacsko


When the scheduler is restarted, ID are always counted from 0, which makes IDs not unique. If someone decides to store the events in the database with IDs being a primary key, it will not be possible because of this. 

We should expose extra information to the REST API so that event IDs become unique when they are concatenated. For example:
* Start timestamp
* Random number
* Random UUID
* An ID constructed from the pod's unique ID
* etc.
