Stratara.Outbox.RabbitMQ

License: MIT.

Outbox-pattern command + event dispatch for the Stratara event-sourced stack with a RabbitMQ / Azure Service Bus message-bus implementation. Contains the write-side dispatchers, the outbox-retry worker, the read-side mediator command worker, the message-bus implementations, and the Redis-backed ProjectionReplayState that coordinates dispatch skip during projection replay.

What's in the box

Folder Contents
Outbox/ OutboxOptions, CommandOutboxDispatcher (write-side ICommand fan-out via IMessageBus, falls back to outbox table on bus failure), EventBundleOutboxDispatcher (same for EventBundle), OutboxWorker (hosted service that retries unpublished outbox rows on a polling interval), NullOutboxLock + RedisOutboxLock (IOutboxLock implementations — default no-op for single-instance deployments, Redis-leased distributed lock for multi-replica setups)
Messaging/ RabbitMqBus — IMessageBus over RabbitMQ. Azure Service Bus ships as the sibling Stratara.Outbox.AzureServiceBus package.
Mediator/ MediatorCommandWorker (hosted service that subscribes to the command topic and dispatches into the in-process IMediator)
Projections/ ProjectionReplayState (Redis-backed concrete IProjectionReplayState; dispatchers skip publishing while replay is active)
DependencyInjection/ AddOutboxDispatcher(), AddOutboxWorker(IConfiguration), AddRedisOutboxLock() (opt-in distributed lock), AddProjectionReplayState(), AddMediatorWorker(), AddMessaging()
Diagnostics/Extensions/ LoggerOutboxExtensions, LoggerMessagingExtensions (source-generated logger surfaces)

Quick start

// In your API host:
builder.AddMessaging();                          // IMessageBus + MessagingOptions binding
builder.Services
    .AddOutboxDispatcher()                       // CommandOutboxDispatcher + EventBundleOutboxDispatcher + ProjectionReplayState
    .AddOutboxWorker(builder.Configuration);     // OutboxWorker hosted service (only if this host owns retries)

// In your command worker:
builder.Services
    .AddMediatorWorker();                        // MediatorCommandWorker hosted service

The dispatchers consult IProjectionReplayState.IsReplayActive before each publish and skip dispatch (writing to the outbox table only) while a replay is in progress.

Multi-instance outbox workers

AddOutboxWorker registers NullOutboxLock as the default IOutboxLock — a no-op that preserves the single-instance assumption. For multi-replica deployments call AddRedisOutboxLock() afterwards; it replaces the no-op with a Redis-leased lock (SET stratara:outbox:lock NX EX) so only one replica drains at a time:

builder.AddCaching();                              // registers IConnectionMultiplexer
builder.Services
    .AddOutboxDispatcher()
    .AddOutboxWorker(builder.Configuration)
    .AddRedisOutboxLock();                         // multi-replica safe

The lease defaults to 60 s (OutboxOptions.LockLeaseSeconds). Tune it so it exceeds the worst-case drain duration; otherwise the lock can expire mid-cycle and a peer may start a concurrent drain. Outbox semantics are still at-least-once, so a duplicate publish is recoverable provided handlers stay idempotent.

Dependencies

  • Stratara.Abstractions — for ICommand, IEvent, IMessageBus, ICommandOutboxDispatcher, IEventBundleOutboxDispatcher, IProjectionReplayState, IMessagingIdentifier, IWriteUnitOfWork (used at runtime via the outbox repository).
  • Stratara.Contracts — for EventBundle + CommandEnvelope messages.
  • Stratara.Mediator — MediatorCommandWorker dispatches into the in-process IMediator.
  • Stratara.Sessions — dispatcher hydrates CommandEnvelope from the current session context.
  • Stratara.Shared — for messaging primitives, resilience pipeline names, mapping helpers, and the diagnostics base.
  • RabbitMQ.Client, StackExchange.Redis (replay-state + optional outbox-lock).
  • Microsoft.Extensions.Hosting.Abstractions + Microsoft.Extensions.Options.ConfigurationExtensions — for hosted services + options binding.

The outbox dispatcher persists rows through IWriteUnitOfWork.CreateOutboxRepository — that interface lives in Stratara.Abstractions, but the concrete implementation comes from Stratara.EventSourcing.EntityFrameworkCore. Reference that package alongside this one to get a working stack.

Package Downloads
Stratara.Infrastructure

Infrastructure glue for the Stratara framework — authorization decorators, configuration providers, and DI composition helpers that wire Mediator, Outbox, Identity, and EF Core into a hosted app.
Stratara.EventSourcing.WorkerDefaults

Worker-host wiring composites for the Stratara event-sourced stack. IHostApplicationBuilder extensions (AddBackendServices, AddCommandWorkerServices, AddEventProjectionWorkerServices, AddSagaWorkerServices, AddOutboxWorkerServices) bundle the per-concern DI calls so each worker host opts in with one line.

### Changed

- **License changed from FSL-1.1-MIT to the MIT License.** Stratara is now OSI-approved open
 source — free for any use, including commercial, with no competition clause and no two-year
 conversion delay. The previous Functional Source License (source-available, converting to MIT
 two years after each release) has been replaced outright. Package metadata now declares the
 SPDX expression `MIT` (`PackageLicenseExpression`), so nuget.org renders a standard clickable
 MIT license label instead of an embedded custom-license file. The `LICENSE` file at the repo
 root now contains the standard MIT text and is still bundled into every package. No code or API
 changes accompany this — it is purely a licensing and metadata change. Previously published
 versions (3.0.20 through 3.1.5) remain under the FSL terms they shipped with; this change applies
 to all versions released from here on.
