Vulthil.Messaging.Outbox

Transactional bus-publish outbox for Vulthil.Messaging. Publishes and sends issued while a database transaction is open are captured into the shared outbox table (atomically with the business changes) and relayed to the broker after the transaction commits — eliminating the dual-write problem. A stable message id is carried through, so a redelivered relay is deduplicated by the receiving inbox (end-to-end effectively-once).

When to use

  • A consumer or command writes to the database and publishes an integration event, and the publish must not happen unless the business change commits (and must happen if it does).

Pattern

  • Reuses the shared outbox engine — one OutboxMessages table and one relay serve both in-process domain events and broker messages, routed by an OutboxDestination discriminator.
  • Capture is gated on an ambient transaction: a publish/send with no active transaction is sent directly.
  • A commit-time trigger relays freshly-committed messages promptly; the periodic poll is the backstop.

Usage

builder.AddDbContext<AppDbContext>(config => config
    .UseNpgsql("Default")
    .EnableOutboxProcessing());

builder.AddMessaging(messaging =>
{
    messaging.UseRabbitMq();
    messaging.AddTransactionalOutbox();
});

The application's DbContext must implement ISaveOutboxMessages (a BaseDbContext already does). Capture is relational-only (it needs a transaction to enlist in).
