Eno Thereska updated KAFKA-4486:
--------------------------------
Fix Version/s: 0.10.2.0
> Kafka Streams - exception in process still commits offsets
> ----------------------------------------------------------
>
> Key: KAFKA-4486
> URL: https://issues.apache.org/jira/browse/KAFKA-4486
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Affects Versions: 0.10.1.0
> Environment: Java 8
> Reporter: Joel Lundell
> Assignee: Eno Thereska
> Fix For: 0.10.2.0
>
>
> I'm building a streams application and would like to be able to control the
> commits manually using ProcessorContext#commit() from an instance of
> org.apache.kafka.streams.processor.Processor.
> My use case is that I want to read messages from a topic and push them to AWS
> SQS and I need to be able to guarantee that all messages reach the queue at
> least once. I also want to use SQS batching support so my approach at the
> moment is that in Processor#process i'm saving X records in a data structure
> and when I have a full batch I send it off and if successful i commit. If I
> for any reason can't deliver the records I don't want the offsets being
> committed so that when processing works again I can start processing from the
> last successful record.
> When I was trying out the error handling I noticed that if I create a
> Processor and in the process method always throw an exception that will
> trigger StreamThread#shutdownTaskAndState which calls
> StreamThread#commitOffsets and next time I run the application it starts as
> if the previous "record" was successfully processed.
> Is there a way to achieve what I'm looking for?
> I found a similar discussion in
> https://issues.apache.org/jira/browse/KAFKA-3491 but that issue is still open.
