> Key: KAFKA-5216
> URL: https://issues.apache.org/jira/browse/KAFKA-5216
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Affects Versions: 0.10.2.0, 0.11.0.0
> Reporter: Xavier Léauté
> Assignee: Xavier Léauté
>
> {{AbstractMergedSortedCacheStoreIterator}} uses the wrong cache key
> deserializer in {{peekNextKey}}. This may result in errors or incorrect keys
> returned from {{peekNextKey}} on a {{WindowStoreIterator}} or
> {{SessionStoreIterator}} for a cached window or session store.
> CachingKeyValueStore does not seem to be affected.
