[infinispan-dev] Fwd: [hibernate-dev] Spring Cache Abstraction

The rest is not really new so all old school issues apply. As usual for higher level caching you need to manually handle data eviction which is likely be a source of bugs. They also don't say if they share the same entity instance or serialize / deserialize but unless this is read-only results (ie not modifiable by the user), you'd better be careful. Likewise, make sure you have a multi-threaded implementations of the data structure returned. They don't seem to discuss transaction or clustering. I imagine they let the underlying cache provider do the work. More specifically with Hibernate, if you use such facility within a open session in view pattern, expect weirdness to happen as well as method level cached objects are not going to be managed entities: - not updated transparently - the same instance might be reattached to several session => badaboom A good summary of where cache could happen in an application is available here http://docs.jboss.org/seam/2.2.1.Final/reference/en-US/html_single/#cache Due to all the potential issues, I tend to favor HTML page fragment caching: - it's higher up the food chain hence likely more efficient - many of the issues declared above don't apply (not all disappear though) But it's sure a useful tool for niche requirements that can live with such constraints.
