Class QueryTimeoutEvent

java.lang.Object

io.hypersistence.optimizer.core.event.AbstractEvent

io.hypersistence.optimizer.hibernate.event.query.QueryEvent

io.hypersistence.optimizer.hibernate.event.query.QueryTimeoutEvent

All Implemented Interfaces:

DurationAwareEvent, Event, Serializable

public class QueryTimeoutEvent
extends QueryEvent
implements DurationAwareEvent

The QueryTimeoutEvent indicates that one of the application queries has been running for more than the maximum allowed time threshold, which is given by the Config.Property.Query.TIMEOUT_MILLIS property value. Long-running queries should be avoided because they impact user experience, consume resources, and prevent other concurrent requests from using the acquired resources (e.g., database connections).

Since:

2.5.0
