Subject [jira] Commented: (JCR-1237) Change default value for respectDocumentOrder
Date Tue, 27 Nov 2007 19:15:43 GMT

Christoph Kiehl commented on JCR-1237:
--------------------------------------

+1 to change the default for "respectDocumentOrder" to "false". Most people don't care about
document order but about performance and they should get the best performance as possible
by default. It's better to let the minority find out how to enable document order than to
let the majority find out how to make jackrabbit perform better.
I think the descriptor should just tell that document order is not supported. Anyone can still
enable it for whichever workspaces they like.

> The current default value for the search index configuration parameter respectDocumentOrder
is true. Almost all applications are not interested in document order, while this default
adds significant overhead to query execution because document order information is present
in the index but has to be calculated over the complete result set.
> I propose to change the default value to false and document this change in the 1.4 release
notes. If an application relies on document order one can still explicitly set the parameter
in the configuration to true.
