The region factory's class name is one.microstream.cache.hibernate.CacheRegionFactory. It is configured via the property hibernate.cache.region.factory_class.

Depending on your environment it can be configured in different ways.

If you use a good old persistence.xml, set the property there:

persistence.xml
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1"
xmlns="http://xmlns.jcp.org/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">
<persistence-unit name="...">
<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
...
<properties>
...
<property name="hibernate.cache.region.factory_class"
value="one.microstream.cache.hibernate.CacheRegionFactory" />
...
</properties>
</persistence-unit>
</persistence>

Or for Spring applications:

application.properties
application.yml
application.properties
spring.jpa.properties.hibernate.cache.microstream.missing_cache_strategy=create
spring.jpa.properties.hibernate.cache.region.factory_class=one.microstream.cache.hibernate.CacheRegionFactory
spring.jpa.properties.hibernate.cache.use_query_cache=true
spring.jpa.properties.hibernate.cache.use_second_level_cache=true
spring.jpa.properties.javax.persistence.sharedCache.mode=ALL
