Subject [jira] Commented: (FOR-711) Cache results from the Locationmap
Date Fri, 10 Feb 2006 16:02:57 GMT
    [ http://issues.apache.org/jira/browse/FOR-711?page=comments#action_12365912 ] 

Ross Gardler commented on FOR-711:
----------------------------------

Following on the AggregatedValidity trial (no idea how Cocoon caching works, so I'm just dumping
ideas at present)...

org.apache.cocoon.components.source.impl.MultiSourceValidity describes itself as:

<p>An aggregated {@link SourceValidity} for multiple sources.</p>

Now the question is, can an InputModule use these sitemap component cache tools - I'm guessing
there is a reason the XMLFileInputModule doesn't use these classes...

> Now that we are using the locationmap extensively it is showing up just how innefficient
it is. The problem is that for the majority of requests there are multiple reqeuests to the
locationmap. We can make things much faster (especially on the first page request) by caching
results in the locationmap.
> I think a simple cache will sufice, lets just provide a static hashmap using the hint
as a key and, of course, the location as the value.
> If we test all locationmaps and find no result we should record that tere is no result
in this hashmap. This will also be a good place to throw an exception so that Cocoon can better
report such errors (see FOR-701)
