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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
