Subject [jira] [Updated] (KAFKA-6487) ChangeLoggingKeyValueBytesStore.all() returns null
Date Thu, 25 Jan 2018 21:12:00 GMT

     [ 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
