> The {{ContinuousFileReaderOperator}} does not correctly deal with watermarks, i.e. they are just passed through. This means that when the {{ContinuousFileMonitoringFunction}} closes and emits a {{Long.MAX_VALUE}} that watermark can "overtake" the records that are to be emitted in the {{ContinuousFileReaderOperator}}. Together with the new "allowed lateness" setting in window operator this can lead to elements being dropped as late.
> Also, {{ContinuousFileReaderOperator}} does not correctly assign ingestion timestamps since it is not technically a source but looks like one to the user.
