--------------------------------------
Summary: Add type filtering & recent events to the REST interface
Key: YUNIKORN-1939
URL: https://issues.apache.org/jira/browse/YUNIKORN-1939
Project: Apache YuniKorn
Issue Type: Sub-task
Components: core - scheduler
Reporter: Peter Bacsko
Assignee: Peter Bacsko
Based on an internal discussion, we need to add extra convenience features to
the REST interface.
1. Filtering: one might be interested in application-only events. We don't
know when the first event belonging to an app was submitted and if the job runs
for hours or days, it's difficult to efficiently retrieve only those which we
want. We can rely on the ID but the client has to store it. It's way better if
we can specify the event type and possibly more details like appID or queue
name (ObjectID).
2. Recent "n" events, the implementation of this is not difficult. We calculate
the startID based on how many events we want. Right now this cannot be done
reliably because right after we determined the startID, new events can arrive,
so the last "n" is no longer the last "n".
