Description Steffen Pingel CLA 2007-10-26 20:17:44 EDT 
Bugzilla queries the repository for changed files before running queries. If queries were run first the query for looking for changed tasks would only have to take the tasks into account that were not returned as query results making that query smaller.
Comment 1 Eugene Kuleshov CLA 2007-10-26 21:00:30 EDT 
Haven't we already been trough this? It is sort of chicken and the egg issue. For example, if a *single* "changed tasks" query returns no tasks then there won't be need to synchronize several other queries for the same repository. This is, of course, also a speculation, unless we'll capture the real performance numbers...
Comment 2 Steffen Pingel CLA 2007-11-01 21:13:19 EDT 
Rob, it seems that in order for this to work we would need a modification time stamp in the query results. It seem that the rdf feed does not provide that. If I set to ctype to rss the timetstamp returned looks like this:

 <updated>2007-10-26T18:00:13Z</updated>
 
Unfortunately the rss feed does not provide the other required fields (severity, priority...), so I don't see how we can make this work.
