FileSystem Implementation for Papst.EventStore

File system based implementation of the Papst.EventStore. This implementation is intended for testing and demonstration purposes only - it is not recommended for production use.

Usage

High-Level Event Store (IEventStore)

IServiceCollection services = new ServiceCollection();
var config = new ConfigurationBuilder()
    .AddInMemoryCollection(new Dictionary<string, string> { { "Path", "/path/to/events" } })
    .Build();

services.AddFileSystemEventStore(config.GetSection("EventStore"));

var serviceProvider = services.BuildServiceProvider();
var eventStore = serviceProvider.GetRequiredService<IEventStore>();

Low-Level Event Store (ILowLevelEventStore)

For handling events as raw JSON objects without type information:

var lowLevelEventStore = serviceProvider.GetRequiredService<ILowLevelEventStore>();
var streamId = Guid.NewGuid();
var stream = await lowLevelEventStore.CreateAsync(streamId, "MyAggregate");

// Append a low-level event (as JObject)
var evt = JObject.Parse(@"{ ""fileData"": ""content"" }");
await stream.AppendAsync(Guid.NewGuid(), "FileCreated", evt);

Deleting an Event Stream

DeleteAsync recursively deletes the stream's directory (its index file and all event files) from disk:

await eventStore.DeleteAsync(streamId);

This is a permanent, hard delete of the on-disk files. If the stream directory does not exist, an EventStreamNotFoundException is thrown. The delete action is logged at Information level.

Configuration

The FileSystem implementation requires a configuration section with the path where events will be stored:

"EventStore": {
  "Path": "/path/to/events/directory"
}

Events are stored as JSON files organized by stream ID in the configured directory.

Important Notes

  • This implementation stores events on the local file system
  • Not suitable for production use
  • Best used for testing, prototyping, and demonstration purposes
  • Events are stored as JSON files; concurrent access must be managed carefully
