Martin Liesenberg commented on FLINK-3404: ------------------------------------------ I have been looking at this task recently and just want to make sure I understand it correctly: there are a {{close}} and a {{cancel}} method already. the difference of the {{stop}} method would be the issuing of the checkpoint, right? > Extend Kafka consumers with interface StoppableFunction > ------------------------------------------------------- > > Key: FLINK-3404 > URL: https://issues.apache.org/jira/browse/FLINK-3404 > Project: Flink > Issue Type: Improvement > Components: Kafka Connector > Reporter: Matthias J. Sax > > Kafka consumers are not stoppable right now. To make them stoppable, they > must implement {{StoppableFunction}}. Implementing method {{stop()}} must > ensure, that the consumer stops pulling new messages from Kafka and issues a > final checkpoint with the last offset. Afterwards, {{run()}} must return. > When implementing this, keep in mind, that the gathered checkpoint might > later be used as a savepoint. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
