You have a domain object, perhaps for reporting purposes, that's built from a ton of JDBC queries and it takes too long to load. Nothing else happens until this object is built, so it's become a bottleneck. Even worse, each of the queries is actually well tuned, so there isn't much to gain from modifying the queries themselves - there are just too many of them. You don't want to change (or can't change) your data model, so what can be done to alleviate this problem short of a major redesign? There are several options like caching, lazy loading, resource pooling. Another worthy option would be to implement a variation of the concurrent query pattern.<p><a href="http://andypardue.sys-con.com/node/313540" target="_blank">read more</a></p> Sun, 24 Dec 2006 22:00:00 EST http://andypardue.sys-con.com/node/313540 http://andypardue.sys-con.com/node/313540#feedback
