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

[Max R. A. <max...@jb...>]

Hi Mahen,

some have previously talked about utilizing the statistics and aop to  
figure
out more optimal ways of querying/mapping so it is not a new idea; just  
that
noone have yet had the time to investigate into it.

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 ;)
