Subject [jira] Created: (JCR-145) Document order of result nodes should be configurable
Date Thu, 23 Jun 2005 08:01:24 GMT
Document order of result nodes should be configurable
-----------------------------------------------------

         Key: JCR-145
         URL: http://issues.apache.org/jira/browse/JCR-145
     Project: Jackrabbit
        Type: Improvement
  Components: query  
 Environment: svn revision: 193102
    Reporter: Marcel Reutegger
    Priority: Minor


Queries without an order by clause are performed with document order for the result nodes.
This is a quite expensive operation, because the document order is available in the search
index itself. The document order is calculated with the help of the ItemStateManager and requires
loading of all result node states including their ancestors.

Queries with a lot of result nodes become quite expensive, even though the actual query execution
is fast. Because most use cases will not care for the document order, this feature should
be made configurable. Some parameter for the QueryHandler that disables the document order
on result nodes.
