[hibernate-dev] Second-level cache and Inheritance

[Vlad Mihalcea]

Hi,

I bumped into this question on our forum:

https://forum.hibernate.org/viewtopic.php?f=1&t=1043470

And after I tried an example using the latest Hibernate version I see that,
for inheritance, all subentities share the parent region name.
This can  be found in org.hibernate.internal.CacheImpl

final String cacheRegionName = cacheRegionPrefix +
model.getRootClass().getCacheRegionName();


As you can see, we take the rootClass when constructing the region name.
For this reason, we cannot use different CacheConcurrencyStartegy with
different subclass types.

Is there any reason for this, or should we consider adding support for this
feature?
