Change Event Service

Change Event Service

This service is web service that provides a RESTful API for creating, deleting and querying change events.

How it Works?

This project written with Flask web framework. It use flask-smorest for REST API, Pyctuator for actuator endpoint and Flask-SQLAlchemy for handle DB queries. Swagger UI documentation and API validations handled by flask-smorest itself. flask-smorest uses Marshmallow schemas for marshalling and unmarshalling objects in request and response. This schemas also used by Swagger UI.

With Flask-APScheduler, a background job started to consume change events from the queue using Pika and persist them to the database.
