Peter Bacsko updated YUNIKORN-1939:
-----------------------------------
Description:
Based on an internal discussion, we need to add an extra convenience features
to the REST interface.
We'd like to retrieve the 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".

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".
