Varun Saxena commented on YARN-6027:
------------------------------------
bq. This should not happen. There should be exactly one row for a flow on a
given day.
Yes. I think they were retrieving data based on last 24 hours instead of
specific dates. That's why duplicate records came.
bq. We do have a lot of runs of a flow on a given day, for instance hRaven is
running constantly on our cluster. So we do expect several runs of a flow in a
day.
How many do we expect typically ? Can it run into thousands ? I had raised a
JIRA to limit flow runs within a flow. We should probably have that support
then.

> In YARN-5585 , fromId is supported for retrieving entities. We need similar
> filter for flows/flowRun apps and flow run and flow as well.
> Along with supporting fromId, this JIRA should also discuss following points
> * Should we throw an exception for entities/entity retrieval if duplicates
> found?
> * TimelieEntity :
> ** Should equals method also check for idPrefix?
> ** Does idPrefix is part of identifiers?
