-----------------------------
Resolution: Fixed
> Default configuration for monthlyIndexOverride is wrong, could cause major
> data integrity issues when upgrading
> ---------------------------------------------------------------------------------------------------------------
>
> Key: UNOMI-480
> URL: https://issues.apache.org/jira/browse/UNOMI-480
> Project: Apache Unomi
> Issue Type: Bug
> Components: core
> Affects Versions: 1.5.5
> Reporter: Serge Huber
> Assignee: Serge Huber
> Priority: Critical
> Fix For: 1.5.6
>
>
> The default value for the following setting:
> {code}
> <property name="itemsMonthlyIndexedOverride"
> value="${es.monthlyIndex.itemsMonthlyIndexedOverride}" />
> {code}
> does not work properly because since the referenced value doesn't exist
> Blueprint uses the marker as a value instead of an empty string (was
> expected).
> The consequence is that the event and session item types are not monthly
> indexes anymore, which has the following consequences:
> - existing data sets will create a new context-event and context-session index
> - all old context-event-date-* and context-session-date-* indices will no
> longer be used and queries for the data will not work
> - external tools such as Kibana will not work either
> As this is a major data model bug, it is being flagged critical and a special
> release will be prepared for it. It is recommended that all users avoid using
> 1.5.5 and wait for 1.5.6 instead.
