Part of the Kodo JDO Performance Pack includes the datastore cache. This appendix discusses integrations of the Kodo datastore cache to thrid party caching solutions.
The Kodo JDO data cache can integrate with Tangosol's Coherence caching system. To use the Tangosol integration, set the kodo.DataCache configuration property to tangosol, with the appropriate plugin properties for your Tangosol setup. For example:
The Tangosol cache understands the following properties:
TangosolCacheName: The name of the Tangosol Coherence cache to use. Defaults to kodo.
ClearOnClose: Whether the Tangosol named cache should be completely cleared when the PersistenceManagerFactory is closed. Defaults to false.
TangosolCacheType: The type of Tangosol Coherence cache to use (optional). Valid values are named, distributed, or replicated. Defaults to named, which means that the cache is looked up via the com.tangosol.net.CacheFactory.getCache(String) method. This method looks up the cached by name as defined in the Coherence configuration.

Note As of this writing, it is not possible to use a Tangosol Coherence 1.2.2 distributed cache type with Apple's OS X 1.3.1 JVM. Use their replicated cache instead.
The Kodo JDO query cache can also integrate with Tangosol's Coherence caching system. To use the Tangosol integration, set the kodo.QueryCache configuration property to tangosol, with the appropriate plugin properties for your Tangosol setup. For example:
Example F.2. Tangosol Query Cache Configuration
kodo.QueryCache: tangosol(TangosolCacheName=kodo-query)
The Tangosol query cache understands the same properties as the data cache, with a default Tangosol cache name of kodo-query.
