Interface DurationAwareEvent

All Superinterfaces:

Event

public interface DurationAwareEvent
extends Event

The DurationAwareEvent is an optional interface that can be implemented by Event types that carry a duration (e.g. a slow-running query or a long-running Session or transaction).

When the event persistence feature is enabled, the reported duration is accumulated into the total_duration_ms column of the runtime rollup, so that a slow operation triggered many times can be summarized rather than stored one row per occurrence.

Since:

2.14.0
