> If a row has been deleted at time stamp 'T' and a scan with time range (0, T-1) is executed,
it still returns the delete marker at time stamp 'T'. It is because of the code in ScanQueryMatcher.java
> {code}
>       if (retainDeletesInOutput
>           || (!isUserScan && (EnvironmentEdgeManager.currentTimeMillis() - timestamp)
<= timeToPurgeDeletes)
>           || kv.getMemstoreTS() > maxReadPointToTrackVersions) {
>         // always include or it is not time yet to check whether it is OK
>         // to purge deltes or not
>         return MatchCode.INCLUDE;
>       }
> {code}
> The assumption is scan (even with setRaw is set to true) should respect the filters and
the time range specified.
> Please let me know if you think this behavior can be changed so that I can provide a
patch for it.
