Subject [jira] [Commented] (APEXMALHAR-2276) ManagedState: value of a key does not get over-written in the same time bucket
Date Thu, 06 Oct 2016 17:08:20 GMT

    [ https://issues.apache.org/jira/browse/APEXMALHAR-2276?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15552532#comment-15552532

Chandni Singh commented on APEXMALHAR-2276:
-------------------------------------------

I don't see a problem. In Scenario A, it is evident right at the time of insertion that update
is old and is ignored.
In Scenario B, it is unknown at the time of insertion that update is old.

Which is why I mentioned, that the client needs to do a get() and then put(). 

ManagedStateImpl and ManagedTimeStateImpl are not for maintaining time series in memory.

> For example:
> ManagedTimeUnifiedStateImpl mtus;
> mtus.put(10000, key1, val1)
> mtus.put(10000, key1, val2)
> mtus.get(10000, key1).equals(val2) will return false
