kadirdemirkaya / Saga-Pattern

Saga pattern is an event-based sample project for a microservice in this project.

Saga Pattern

This project was done by using two different types (EventChoreography, Orchestration) in accordance with the saga pattern rules.

EventChoreography

Event choreography is a model that describes the interaction of individual services in a system. Services use events to communicate with each other and coordinate operations.

• Projects inside
  • BasketAPI
  • OrderAPI
  • PaymentAPI
  • StockAPI
  • SharedLIBRARY

Orchestration

Orchestration is a model that centrally manages and coordinates operations in a system. A master service or orchestrator directs other services and performs operations in a specified order and according to rules

• Projects inside
  • BasketAPI
  • OrderAPI
  • PaymentAPI
  • SharedLIBRARY
  • StateMachineWorkerService
  • StockAPI

Run on Your Computer

Clone the project

  git clone https://github.com/kadirdemirkaya/SagaPattern.git

Make your own changes to the .json file

  appsettings.json
  appsettings.Development.json

Go to the project directory of the API projects and create a migration

  cd BasketAPI
  cd OrderAPI
  ...

Then enter the directory of all api projects and stand up the server

  dotnet run

Features

• Basket is created and data is sent in BasketAPI
• OrderAPI receives cart data and, depending on the situation, cancels or sends data for stock control
• If the stock is sufficient, data will be sent again for payment or canceled
• If the payment is made successfully in PaymentPI, the data is confirmed in the database or canceled in all services.
• The common library contains the data that all API services will use.
• MSSQL was used for all these operations
• The same events are handled in two different ways (EventChoreography and Orchestration)
