I added one more inline comment. > Fix Streaming File Source Timestamps/Watermarks Handling > -------------------------------------------------------- > > Key: FLINK-4329 > URL: https://issues.apache.org/jira/browse/FLINK-4329 > Project: Flink > Issue Type: Bug > Components: Streaming Connectors > Affects Versions: 1.1.0 > Reporter: Aljoscha Krettek > Assignee: Kostas Kloudas > Fix For: 1.1.1 > > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
