    Hi @rtudoran, I had a look at the PR and left a comment on [FLINK-6075](https://issues.apache.org/jira/browse/FLINK-6075).
    
    I think we do not need retraction for `OFFSET` and `FETCH` on `ORDER BY *time ASC` and
can implement this by extending the existing `ProcessFunction` for sorting. We only need to
buffer and retract rows if we support `OFFSET` and `FETCH` for arbitrary sort orders.
    
    Let me know what you think,
    Fabian
