SQL Remote Code Execution Engine

Welcome to the SQL Remote Code Execution Web Application repository! This project is a powerful yet user-friendly web-based application designed to streamline the process of executing SQL queries and visualizing their results. It can be used by a developer, a data analyst, or a database administrator, our application provides an intuitive interface for interacting with databases and retrieving valuable insights from your data.

Features

Frontend is built using React and Ant Design, offering a clean and intuitive interface for users to input their SQL queries. The interface accepts the input from the user and runs the sql query against that input. The result then shows up in a table

The backend, constructed with Node.js, is augmented by Redis to efficiently manage user sessions. Redis ensures individual user isolation by assigning distinct databases to each user. Inactivity is addressed through a scheduler that automatically disengages user databases after a 10-minute period, freeing up resources for new users. Currently, the system accommodates up to 4 concurrent users. Moreover, the system's architecture is readily scalable horizontally, enabling seamless expansion to handle higher loads. The diagram below provides a comprehensive visualization of the system's design:

Below is the loadtime of the application. Since it's a not so UI intensive but if it was we can make the UI loads in less amount of time using Code Spliting/ Lazy Loading in react. I've saperated the codes in different components for the current scenario so to make application more performant.
