This repository contains code that is based on the RAFT Algorithm for a Primary-Backup System. We have provided a way to interact with the system via terminal or using a Flask app. Please see the instructions below to run the system:

Run via Terminal

1. Clone this repository locally using git clone https://github.com/joudelshawa/RAFT_implementation_CS4459.git
2. In your local location, run pip install -r requirements.txt
3. Ensure redis is on using redis-server
4. Then run python server_manager.py and play around with the system! You can add servers using start server 1, where 1 can be replaced with any positive integer, remove servers using stop server 1 or stop all, and input (write) data using input key value, where key and value can be any strings.

Run Flask App

Do NOT force shut down the Flask App before killing all active servers!

1. Clone this repository locally using git clone https://github.com/joudelshawa/RAFT_implementation_CS4459.git
2. In your local location, run pip install -r requirements.txt
3. Ensure redis is on using redis-server
4. Run cd flask
5. Run python app.py and open the corresponding localhost link (e.g., http://127.0.0.1:5000) and start playing around with the system! You can add servers using the add server button, which will automatically add new servers without needing server IDs (they will monotonically increase), remove servers using the kill server button on each server card, and input (write) data using the input bar by providing key value and pressing enter, where key and value can be any strings.

Happy logging!
