[hibernate-dev] Re: [Hibernate] Fwd: hibernate performace improvements and dynamicmappings generation using heuristics

hi, Appreciate if someone can give me some pointers on where i can find a Hibernate Developers guide, as in some document(s) which will help in developing and analysing the hibernate codebase.

I would assume classic database query optimizing techniques and program flow analysis is applicable in this area so if you know those then simply learn hibernate and apply them ;) /max > Hi All, > > I am a postgraduate student from Imperial College, London,, > > I am doing a research on performace optimisations in the peristence > layer of > a web > application... > > just want to get your ideas on likely improvements that can be done in > hibernate to > optimise the performance,, > these changes should be changes to the hibernate core... > > yeah,, i have seen various articles on how to increase performace in > hibernate and all,, but > what i want to know is that what are the areas that i can explore in > order > to increase > the performance more..at the code level > > i am hoping to try out various optmisations and evaluate the likely > impact > of each > optimisation and stuff like that and would like to contribute to > hibernate > with my > findings,,, > > greatly appreciate some pointers from you all,, > > mainly i am concerned about the following disadvantage of hibernate: > > > "Developers must know enough information about data usage at compile > time to > be able to optimise queries and choose the appropriate object-relational > mappings" > so therefore, i am thinking about the repercussions and advantages of > having dynamically generated mapping files based on heuristics of the > usage > pattern of the data,, in other words dynamically deciding on the mapping > based on what queries are used more frquently in a system,, > > would appreciate some feedback from you all > > Thanks > Mahen -- -- Max Rydahl Andersen callto://max.rydahl.andersen Hibernate max(a)hibernate.org <mailto:max@hibernate.org> http://hibernate.org JBoss a division of Red Hat max.andersen(a)jboss.com <mailto:max.andersen@jboss.com> ------------------------------------------------------------------------ ------------------------------------------------------------------------- Using Tomcat but need to do more?
