Manish Baxi updated HIB-199:
----------------------------
Attachment: andromda-hibernate-cartridge-3.2.jar
> Enabling caching of objects should not enable it for all entities
> -----------------------------------------------------------------
>
> Key: HIB-199
> URL: http://jira.andromda.org/browse/HIB-199
> Project: Hibernate Cartridge
> Type: New Feature
> Versions: 3.2-RC1
> Reporter: Manish Baxi
> Assignee: Carlos Cuenca
> Priority: Critical
> Attachments: andromda-hibernate-cartridge-3.2.jar
>
> We have an application with thousands of entities, out of which about 100 are
> meant to store static or reference data while the others are purely
> transactional in nature and change too frequently. There is a strong
> business case to cache objects of static or reference types but not of the
> transactional type.
> Before we started using AndroMDA, we were already using HIBERNATE and EHCACHE
> and had caching enabled for individual classes where caching was required.
> After moving to AndroMDA we have discovered that it isn't possible to turn
> caching on for individual objects. This is quite painful for us as right now
> we desperately need caching but turning it on forces entries for all entities
> into the ehcache.xml file although we do not want that behaviour.
> My suggestion is that besides the property that controls caching in the
> Namespace, another property be added to the Profile that will allow us to
> control caching of individual entities through the tagged values. An entry
> should be made to ehcache.xml only if the property is set both in the
> namespace and the profile for an entity.
> Right now I have specified cache-type=none in andromda.xml and then
> overridden it in tagged values for the entities where I need caching. I have
> also modified the cartridge locally to check whether cache-type is set to
> something other than none and only then generate a cache entry for that
> entity.
