Question 1

How to set up Silverback with Kafka in .NET Core?

Accepted Answer

Use the AddSilverback() method in Startup, configure Kafka clients with bootstrap servers, and define producers/consumers for topics, as shown in the quick example in the README. Detailed guides are on the documentation site.

Question 2

Silverback vs MassTransit for .NET messaging?

Accepted Answer

Silverback is Kafka-first with deep integration for Kafka features, while MassTransit supports more brokers like RabbitMQ and Azure Service Bus but may abstract Kafka specifics. Choose Silverback for Kafka-heavy systems; MassTransit for broader broker support.

Question 3

Does Silverback support RabbitMQ?

Accepted Answer

No, Silverback only supports Apache Kafka and MQTT natively, as stated in the README. For RabbitMQ, you'd need to use alternatives like MassTransit or custom integrations.

Question 4

How to handle message errors in Silverback?

Accepted Answer

Silverback includes configurable error policies, such as retry strategies and dead-letter queues, which can be set up through options when defining consumers, ensuring reliable error handling.

Question 5

Can I use Silverback for IoT projects with MQTT?

Accepted Answer

Yes, Silverback has first-class MQTT support via the Silverback.Integration.Mqtt package, making it suitable for IoT applications requiring lightweight messaging and broker integration.

Question 6

What are the performance costs of using transactional outbox in Silverback?

Accepted Answer

The transactional outbox adds storage overhead and potential latency due to dual writes, but it ensures message reliability in distributed transactions, as highlighted in the 'Reliable by design' feature.
