---------------------------------------
Summary: Streaming File Source Must Correctly Handle
Timestamps/Watermarks
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
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.
