Hibernate: 3.0

Hi All,

I’ve been reading Java Persistence with Hibernate, very nice book by the way.

It talks about n+1and Cartesian product problems.

Do these problems still apply if using a L2 Cache and there is an embedded copy of the cache inside the application?

Just to clarify this point we are developing an application that uses Gigaspaces technology for level 2 Hibernate cache. There is a remote master space and also a embedded local spaces (within the same memory space of the application) that contains a copy of the master, that’s ok as the database is small enough.

Thanks for your help.

When running a in a master local topology you should remember that insert/update operations would be relatively expensive. This would need to go both into the remote space , update the local cache and also go into the database in serial manner.

note the the local space is sync with the master copy via notifications that are async by nature. So there will be a small delay between the master copy update and the local copy update.
