Chandni Singh commented on APEXMALHAR-2276:
-------------------------------------------
Yes time gets mapped to a time bucket, however the exact value of time is lost
and currently we cannot derive time from the timebucket.
This affects cases where we want to save the most recent value of a key. In
use-cases, like de-duplication/aggregation this is not the case.
In De-duplication we check whether there is a key present and drop the event if
its duplicate.
In Aggregation, we use the existing value in the time-bucket and aggregate it
with new value.
> ManagedState: value of a key does not get over-written in the same time bucket
