Saga Orchestration Project

It integrates with MassTransit and RabbitMQ to provide reliable transaction coordination in distributed systems.

Features

Saga State Machine:

• Manages the status of stock orders (Pending, Approved, Rejected) using a state machine.
• State transitions are triggered asynchronously via RabbitMQ messages.

Order Processing:

• Receives the order and forwards it to the stock service for validation.
• Ensures the order flows seamlessly into the stock validation phase.

Stock Processing:

• Verifies stock availability before proceeding to payment.
• If stock is insufficient, the process terminates and marks the order as Rejected.
• If stock is sufficient, the order proceeds to the payment step.

Payment Processing:

• If payment succeeds, the order is approved; otherwise, it is rejected.

MassTransit for Saga Management:

• Ensures reliable coordination between order and payment processes.
• Utilizes RabbitMQ as the messaging system.

Technologies Used

• MassTransit: For saga orchestration and messaging.
• RabbitMQ: For inter-service messaging in distributed systems.
• .NET 8: For developing the project.
• MongoDB: For database operations of the Stock service.
• MSSQL: For database operations of the Order service and Masstransit.
