13.1.1. RegionFactory

<div class="paragraph">

`org.hibernate.cache.spi.RegionFactory` defines the integration between Hibernate and a pluggable caching provider.
`hibernate.cache.region.factory_class` is used to declare the provider to use.
Hibernate comes with built-in support for the Java caching standard [JCache](#caching-provider-jcache)
and also two popular caching libraries: [Ehcache](#caching-provider-ehcache) and [Infinispan](#caching-provider-infinispan).
Detailed information is provided later in this chapter.
