> Project: Samza
> Issue Type: Bug
> Reporter: Yi Pan (Data Infrastructure)

> Priority: Major
>
> We have encountered a bug in Kafka 0.11 that when a topic is configured to
> use a combination of cleanup policy delete+compact, the broker enters a
> deadlock situation.
> Currently, we set the delete+compact policy for changelog topics in batch
> jobs to reduce the storage requirement and the additional GC effort required.
> However, before the above mentioned Kafka bug is fixed, we will disable this
> feature for now.
