Class NoSnapshotStrategy

Namespace: Stratara.Infrastructure.EventSourcing

Assembly: Stratara.Infrastructure.dll

ISnapshotStrategy that never writes a snapshot — the supported way to disable snapshotting globally. Streams are always rebuilt by replaying their full event history.

public sealed class NoSnapshotStrategy : ISnapshotStrategy

Inheritance: object

NoSnapshotStrategy

Implements: ISnapshotStrategy

Inherited Members: object.Equals(object)

object.Equals(object, object)

object.GetHashCode()

object.GetType()

object.ReferenceEquals(object, object)

object.ToString()

Extension Methods: FieldChangedEventExtensions.ApplyPropertyChanged<TAggregate>(TAggregate, FieldChangedEvent<TAggregate>)

EventStream.ApplyEvents(object, IReadOnlyList<IEvent>)

Remarks

Register with services.AddSingleton<ISnapshotStrategy, NoSnapshotStrategy>() to override the default VersionThresholdSnapshotStrategy. Useful for short-lived aggregates, tests, or deployments where snapshot storage is undesirable.

Methods

ShouldSnapshot(Type, long, long)

Determines whether a snapshot should be written for the stream described by the arguments.

public bool ShouldSnapshot(Type aggregateType, long currentVersion, long lastSnapshotVersion)

Parameters

aggregateType Type: The runtime aggregate type of the stream being evaluated.
currentVersion long: The stream's highest version after the events just appended.
lastSnapshotVersion long: The version of the most recent existing snapshot for the stream, or 0 when the stream has no snapshot yet.

Returns

bool: true to write a fresh snapshot at currentVersion; otherwise false.
