------------------------------------
Summary: Processors punctuate() methods call multiple times
Key: KAFKA-4181
URL: https://issues.apache.org/jira/browse/KAFKA-4181
Project: Kafka
Issue Type: Bug
Components: streams
Affects Versions: 0.10.0.1, 0.10.0.0
Reporter: James Clinton
Assignee: Guozhang Wang
I'm seeing odd behaviour whereby a Processor's punctuate(..) method is not
invoked based on the schedule, but builds up a backlog of pending punctuate()
calls that get flushed through when the Processors process() method is next
called.
So for example:
1. Schedule the punctuate() methods to be called every second.
2. A minute passes
3. Processor.process() receives a new message
4. Processor.punctuate(..) is invoked 60 times
