public class HibernateEntityRegion extends HibernateTransactionalDataRegion implements org.hibernate.cache.spi.EntityRegion
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)
