Excalibur.EventSourcing

Event sourcing infrastructure for the Excalibur framework.

dotnet add package Excalibur.EventSourcing

Features

• IEventStore - Event stream persistence abstraction
• IEventSourcedRepository<T, TKey> - Repository pattern for event-sourced aggregates
• ISnapshotManager and ISnapshotStrategy - Snapshot support for performance optimization
• IUpcastingPipeline - Event versioning and migration support
• InMemoryEventStore - In-memory implementation for testing

Usage

// Register event sourcing with a provider (SQL Server example)
services.AddExcalibur(x => x.AddEventSourcing(es =>
{
 es.UseSqlServer(opts => opts.ConnectionString = connectionString);
 es.AddRepository<OrderAggregate, Guid>(id => new OrderAggregate(id));
}));

// Or use in-memory for testing
services.AddExcalibur(x => x.AddEventSourcing(es => es.UseInMemory()));

// Use with aggregates
public class OrderAggregate : AggregateRoot<Guid>
{
 public void PlaceOrder(OrderDetails details)
 {
 Apply(new OrderPlacedEvent(Id, details));
 }
}
