Chaos.Mongo.Outbox

GitHub License NuGet Version NuGet Downloads GitHub last commit GitHub Actions Workflow Status

A transactional outbox for MongoDB with typed payloads, at-least-once background delivery, retries, stale-lock recovery, and optional retention cleanup.

Installation

dotnet add package Chaos.Mongo.Outbox

Quick start

Define a payload and publisher:

using Chaos.Mongo;
using Chaos.Mongo.Outbox;

public sealed class OrderPlaced
{
    public string OrderId { get; set; } = string.Empty;
}

public sealed class NotificationsPublisher : IOutboxPublisher
{
    public Task PublishAsync(
        OutboxMessage message,
        CancellationToken cancellationToken = default)
    {
        var payload = message.DeserializePayload<OrderPlaced>();
        return PublishToBrokerAsync(payload, cancellationToken);
    }

    private static Task PublishToBrokerAsync(
        OrderPlaced payload,
        CancellationToken cancellationToken) => Task.CompletedTask;
}

Register the core MongoDB services and outbox processor:

services.AddMongo("mongodb://localhost:27017", "myDatabase")
    .WithOutbox(outbox => outbox
        .WithPublisher<NotificationsPublisher>()
        .WithMessage<OrderPlaced>("OrderPlaced")
        .WithAutoStartProcessor());

Write the business change and message in the same transaction:

await mongo.ExecuteInTransaction(async (helper, session, cancellationToken) =>
{
    await orders.InsertOneAsync(session, order, cancellationToken: cancellationToken);
    await outbox.AddMessageAsync(
        session,
        new OrderPlaced { OrderId = order.Id.ToString() },
        correlationId: order.Id.ToString(),
        cancellationToken: cancellationToken);
});

MongoDB transaction support is required for atomic business and outbox writes. The processor must be started automatically or through IOutboxProcessor for messages to be delivered.

Package relationships

This package references Chaos.Mongo, which provides MongoDB registration and transaction helpers. Chaos.Mongo.EventStore is optional and can add outbox messages through event-store transactional callbacks.
