Ok.
One thing here though. Chris's original solution works in such way
that for each entity/collection, a new cache is retrieved from the
cache manager using the region name, so for this example 3 caches
would be created:
Cache1 for
[org.hibernate.test.cache.infinispan.functional.VersionedItem]
Cache2 for [org.hibernate.test.cache.infinispan.functional.Item]
Cache2 for [org.hibernate.test.cache.infinispan.functional.Item.items]
Can we confirm this is the intented way? In https://jira.jboss.org/jira/browse/ISPN-6
the following is mentioned:
"Use a separate named cache per entity. This cache would hold entity
instances as well as collections pertaining to that entity."
So, if that is followed and we bear in mind the above example, there
should only be 2 cache instances created rather than the current 3.
What is clear is that there's no need for
hibernate.cache.infinispan.cfg.entity or
hibernate.cache.region.ispn4.cfg.collection. Simply stick the
default cache configuration for entity/collections in the default
section of configuration.
I don't we need hibernate.cache.infinispan.cfg.query and
hibernate.cache.infinispan.cfg.timestamps either since we can simply
name the caches with the corresponding region names
(org.hibernate.cache.UpdateTimestampsCache]and
org.hibernate.cache.StandardQueryCache) and that's it.
I suppose that would depend on the need for different eviction
characteristics for different entity types. So from that perspective
(the ability to use) a different cache per entity is useful.
E.g.,
NoEvictionCache for [CountryList]
NoEvictionCache for [SomeOtherDropDown]
AggressivelyEvictedLRUCache for [Users]
AggressivelyEvictedLRUCache for [Orders]
LargeCapacityFIFOCache for [ProductsCatalog]
etc. may well prove useful.
Brian/Steve - care to chime in?
