[jira] [Updated] (KAFKA-6487) ChangeLoggingKeyValueBytesStore.all()
returns null
[ https://issues.apache.org/jira/browse/KAFKA-6487?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Bill Bejeck updated KAFKA-6487:
-------------------------------
Description:
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
