Class SessionFlushTimeoutEvent

java.lang.Object

io.hypersistence.optimizer.core.event.AbstractEvent

io.hypersistence.optimizer.hibernate.event.session.SessionEvent

io.hypersistence.optimizer.hibernate.event.session.SessionFlushTimeoutEvent

All Implemented Interfaces:

DurationAwareEvent, Event, Serializable

public class SessionFlushTimeoutEvent
extends SessionEvent
implements DurationAwareEvent

The SessionFlushTimeoutEvent indicates that the current Persistence Context (EntityManager or Session) has been flushed for more than the maximum allowed time threshold, which is given by the Config.Property.Session.FLUSH_TIMEOUT_MILLIS property value.

The more entities the current Persistence Context is managing, the longer it takes to process the dirty checking mechanism and synchronize the entity state changes with the database.

The flush execution time impacts the overall transaction response time, so you need to make sure that the current JPA EntityManager or Hibernate Session doesn't contain a very large number of entities.

Since:

2.2.0
