[Hibernate] hibernate performace improvements and dynamic mappings generation using heuristics

[Mahen Perera]

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
