JpaAutoFlushListener (Keycloak Docs Distribution 21.0.1 API)

java.lang.Object
- org.hibernate.event.internal.AbstractFlushingEventListener
- - org.hibernate.event.internal.DefaultAutoFlushEventListener
  - - org.keycloak.models.map.storage.jpa.hibernate.listeners.JpaAutoFlushListener

All Implemented Interfaces:

Serializable, org.hibernate.event.service.spi.JpaBootstrapSensitive, org.hibernate.event.spi.AutoFlushEventListener
```
public class JpaAutoFlushListener
extends org.hibernate.event.internal.DefaultAutoFlushEventListener
```
Extends Hibernate's DefaultAutoFlushEventListener to always flush queued inserts to allow correct handling of orphans of that entities in the same transactions, and also to clear a session-level query cache.
If they wouldn't be flushed, they won't be orphaned (at least not in Hibernate 5.3.24.Final). This class copies over all functionality of the base class that can't be overwritten via inheritance. This is being tracked as part of keycloak/keycloak#11666.
This also clears the JPA map store query level cache for the JpaMapKeycloakTransaction whenever there is some data written to the database.
