One other thing that takes time is reflection. I don't know if some calls to
ReflectHelper can be replaced by static code but it would help.
Hum, would be interesting to see if startup is faster when all types are specified in the mapping.
I guess it would then also be possible to delay some classloading....
Without caring about profiling I would have proposed two solutions:Hum yes, perhaps....
1- Have hibernate being sloppier. I think it's doing a lot of validations
when loading the configuration. Maybe we can have a mode where it doesn't do
all that.
2- Lazy load the conf. I mean, don't load every file at the beginning, only
when the session using the configuration needs it. So for instance load a
persistent class only when there's a query on it. Again, a having the two
possibilities will be nice (everything at startup or as needed). However, as
Gavin said, it might not be possible... One cannot guess where is the class
of query he is looking for. It might become possible it we change the
approach. For instance having a addLazyClass(Class persistentClass) method
so you know that it you need the mapping the the class, you know it's in the
hbm.xml having the same name.
This would be really hard. Remember that each class needs to know about all associated classes
to figure out fk types, etc.
P.S.: Something that has nothing to do with what's above. If you have a query "from Player as player where player.team = :team", is it more efficient than "from Player as player where player.team.id = :team" or it doesn't make any difference?
Shouldn't be any difference.
