All Implemented Interfaces:

org.hibernate.cache.spi.ExtendedStatisticsSupport, org.hibernate.cache.spi.Region

public class HibernateEntityRegion
extends HibernateTransactionalDataRegion

Implementation of EntityRegion. This region is used to store entity data.

L2 cache for entity can be enabled in the Hibernate configuration file:

 <hibernate-configuration>
     <!-- Enable L2 cache. -->
     <property name="cache.use_second_level_cache">true</property>

     <!-- Use Ignite as L2 cache provider. -->
     <property name="cache.region.factory_class">org.apache.ignite.cache.hibernate.HibernateRegionFactory</property>

     <!-- Specify entity. -->
     <mapping class="com.example.Entity"/>

     <!-- Enable L2 cache with nonstrict-read-write access strategy for entity. -->
     <class-cache class="com.example.Entity" usage="nonstrict-read-write"/>
 </hibernate-configuration>
 

Also cache for entity can be enabled using annotations:

 @javax.persistence.Entity
 @javax.persistence.Cacheable
 @org.hibernate.annotations.Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
 public class Entity { ... }
