Error Handling and Retries

Handle faults with retry and dead-letter queues.

Failure Is Normal

Consumers fail: a transient database error, a downstream timeout, a bug on bad data. MassTransit provides layered tools (retry, redelivery, error queues) so failures are handled gracefully instead of losing messages.

Immediate Retry

For brief blips, configure retry so MassTransit reprocesses the message a few times in quick succession before giving up.

cfg.ReceiveEndpoint("orders", e =>
{
    e.UseMessageRetry(r => r.Immediate(3));
    e.ConfigureConsumer<OrderConsumer>(context);
});
