Flowly.DeadLetters

Dead letter tracking for Flowly. Captures dead-lettered messages into a database so you can inspect, requeue, or discard them. Requires a database backend package.

Quick Start

Also install a database backend: Flowly.DeadLetters.SqlServer or Flowly.DeadLetters.Postgres.

builder.AddFlowly(configure => configure
    .UseAzureServiceBus("AzureServiceBus")
    .AddSqlServerDeadLetterTracking(
        builder.Configuration.GetConnectionString("DeadLetters")!)
    .AddMessageHandler<OrderCreated, OrderCreatedHandler>()
    .WithDeadLetterTracking());    // opt-in per handler

WithDeadLetterTracking() registers a background service that reads from the broker's dead letter sub-queue and persists records to the DeadLetters database table.

What Gets Stored

Field Description
QueueName The queue the message came from
MessageBody Raw message body (never deserialized)
MessageProperties All metadata headers as JSON
DeadLetteredAt When the message was dead-lettered
DeadLetterReason Broker-provided reason
Status Pending, Requeued, or Discarded

Event Handlers

Dead letter tracking is also supported on EventHandlerBase<TEvent> handlers. The SubscriptionName field identifies which subscriber dead-lettered the event. Requeuing re-publishes to the topic so only the originating subscriber receives the message.
