Broker Topology
With RabbitMQ, which supports exchanges and queues, messages are sent or published to exchanges and RabbitMQ routes those messages through exchanges to the appropriate queues. When the bus is started, MassTransit will create exchanges and queues on the virtual host for the receive endpoint.
How MassTransit works?
When sending a message, MassTransit uses a message serializer to convert message contract instances (objects) into JSON, XML, or whatever output format is generated by the serializer. When receiving that message, a message deserializer is used to convert the formatted data back into the message contract.
Is MassTransit production ready?
And MassTransit is already stable having been used in production since 2008. The format is well documented and has been tested with billions of messages. Furthermore, the envelope includes headers for tracking messages, including conversations, correlations, and requests.
What is MassTransit saga?
A saga is a long-lived transaction managed by a coordinator. Sagas are initiated by an event, sagas orchestrate events, and sagas maintain the state of the overall transaction. Sagas are designed to manage the complexity of a distributed transaction without locking and immediate consistency.

Why should I use MassTransit?
MassTransit includes a high-performance in-memory transport for testing every consumer using the same code that would be used in production. And the MassTransit. TestFramework NuGet package includes test harnesses that handle the setup and teardown of the bus so you can easily test your message consumers and sagas.
What are two types of Saga saga?
There are two types of Saga:
- Choreography-Based Saga. In this approach, there is no central orchestrator.

Sagas maintain data consistency across distributed services using a sequence of local transactions. Each local transaction updates data within a single service. Any service initiates the first step of the saga. The completion of a local transaction triggers the execution of the next local transaction and so on.
What is Saga pattern and how important is it?

Design patterns are divided into three fundamental groups: Behavioral, Creational, and. Structural.
What is the difference between Saga and event sourcing?
Saga pattern can help us maintain the data consistency among the microservices architecture efficiently. Event Sourcing ensures that all changes to business entity’s state are stored as a sequence of events.
Is Saga a database?
A saga is a sequence of local transactions. Each local transaction updates the database and publishes a message or event to trigger the next local transaction in the saga.
