Class HibernateRegionFactory

java.lang.Object

org.apache.ignite.cache.hibernate.HibernateRegionFactory

All Implemented Interfaces:

Serializable, org.hibernate.cache.spi.RegionFactory, org.hibernate.service.Service

public class HibernateRegionFactory
extends Object
implements org.hibernate.cache.spi.RegionFactory

Hibernate L2 cache region factory.

Following Hibernate settings should be specified to enable second level cache and to use this region factory for caching:

 hibernate.cache.use_second_level_cache=true
 hibernate.cache.region.factory_class=org.apache.ignite.cache.hibernate.HibernateRegionFactory
 

Note that before region factory is started you need to start properly configured Ignite node in the same JVM. For example to start Ignite node one of loader provided in org.apache.ignite.grid.startup package can be used.

Name of Ignite instance to be used for region factory must be specified as following Hibernate property:

 org.apache.ignite.hibernate.ignite_instance_name=<Ignite instance name>
 

Each Hibernate cache region must be associated with some IgniteInternalCache, by default it is assumed that for each cache region there is a IgniteInternalCache with the same name. Also it is possible to define region to cache mapping using properties with prefix org.apache.ignite.hibernate.region_cache. For example if for region with name "region1" cache with name "cache1" should be used then following Hibernate property should be specified:

 org.apache.ignite.hibernate.region_cache.region1=cache1
