[jira] [Created] (FLINK-3405) Extend NiFiSource with interface
StoppableFunction
Matthias J. Sax created FLINK-3405:
--------------------------------------
Summary: Extend NiFiSource with interface StoppableFunction
Key: FLINK-3405
URL: https://issues.apache.org/jira/browse/FLINK-3405
Project: Flink
Issue Type: Improvement
Components: Streaming Connectors
Reporter: Matthias J. Sax
Nifi source is not stoppable right now. To make it stoppable, is must implement {{StoppableFunction}}. Implementing method {{stop()}} must ensure, that the source stops receiving new messages from Nifi and issues a final checkpoint. Afterwards, {{run()}} must return.
When implementing this, keep in mind, that the gathered checkpoint might later be used as a savepoint.
