This project is a meeting tool that allows users to create meetings and chat. The tool is built using Redis and a traditional Mysql Database.
- Clone the repository
- Install the dependencies using
pip install -r requirements.txt - Run a local mysql server
- Run a local redis server
- Load the database schema from the file
database.sql - Run the program using 'python UI.py'
The project is developed using Python and the following libraries:
- Redis
- Mysql
In order to achieve the goal of the project, the following classes were created:
- User
- Meeting
- MetingInstance
- RedisConnection
- DataBaseConnection
- UI
- Scheduler
- RedisFunctions
Scheduler is a class that is used to check if there are any meetings that are due to start and if so, it starts them. It also checks if there are any meetings that are due to end and if so, it ends them. In the beggining of the program, Scheduler is started in a separate thread and it runs in the background.
UI is a class that implements interaction with the user. The user types in the function he wants to run along with any required input in the command line. The produced output is displayed in the same CLI.
The main functions of the program are implemented in the RedisFunctions class. This class interacts with the Redis and MySql databases. It is used to create, delete and update meetings and users. It is also used to get the information about the meetings and users.
In order to support chat we used redis pub/sub. When a user joins a meeting, he subscribes to the channel of that meeting. When a user sends a message, the message is published to the channel of the meeting. The channel of each meeting runs in a separate thread the background.
