> Key: KAFKA-6487
> URL: https://issues.apache.org/jira/browse/KAFKA-6487
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Affects Versions: 1.0.0
> Reporter: Bill Bejeck
> Assignee: Bart De Vylder
> Priority: Major
>
> The {{ChangeLoggingKeyValueBytesStore}} implements the {{KeyValueStore}}
> interface which extends the {{ReadOnlyKeyValueStore}} interface. The Javadoc
> for {{ReadOnlyKeyValueStore#all}} states the method should never return a
> {{null}} value.
> But when deleting a record from the {{ChangeLoggingKeyValueBytesStore}} and
> subsequently calling the {{all}} method, a null value is returned.
>
> https://issues.apache.org/jira/browse/KAFKA-4750 is a related issue
