Zhijie Shen commented on YARN-3984:
-----------------------------------
Okay, "e! eventid # inverse_event_timestamp ? eventkey" sounds a reasonable
compromise.
Secondly, how do we deal with an event without any info? How about creating a
column "e! eventid # inverse_event_timestamp ? dummy_key : empty_value"?

> Currently, the event column key is event_id?info_key?timestamp, which is not
> so friendly to fetching all the events of an entity and sorting them in a
> chronologic order. IMHO, timestamp?event_id?info_key may be a better key
> schema. I open this jira to continue the discussion about it which was
> commented on YARN-3908.
