HTTP-based throttling echo service

written by Ege Atesalp

Documentation

POST /echo - Returns as response the JSON body of the request

GET /rate - Returns as response the request limit of the throttling functionality

POST /rate - Changes the request limit of the throttling functionality, returns the updated request limit

Installation

Local

In root directory

Install the required modules in requirements.txt using the preffered dependency manager

    # Pull and run the redis container, skip if already running 
    docker-compose up redis

    
    # Run the app from port 8000, listens Redis from 6379 
    # If running locally, change the host parameter in redis.Redis() to 'localhost'
    python main.py

Docker

    docker-compose up

Testing

In root directory(docker or local)

    pytest

It is normal for the testing to take approximately 65 seconds, since it tests the 60 sliding window of the throttling functionality

Future Improvements

• Improve asynchronous handling
-Comment: Especially important for scalability, better leverages ASGI
• Create individual testing
-Comment: Testing with multiple tests affected the results, specifically because the database values were incosistent inbetween.
• Add functionality to make the middleware (throttling) only handle specific requests (/echo)
