Varun Saxena commented on YARN-6027:
------------------------------------

bq. IIUC, FROM_ID will be different for different storage layers. So, it would be always safer to allow backend storage to add FROM_ID rather than timeline reader encode/decode it. 
Makes sense.

> 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?
