Redis Clone

A lightweight implementation of a Redis-like in-memory data store in Python. This project supports basic Redis commands like PING, ECHO, SET, and GET, as well as key expiration features. It also supports core Redis functionalities like key-value storage, replication, and basic client-server communication.

---

Features

• Commands Supported:
  • PING: Test connectivity with PONG.
  • ECHO: Echo back the provided message.
  • SET: Store a key-value pair in the in-memory store.
    • Optional expiration using EX (seconds) or PX (milliseconds).
  • GET: Retrieve the value of a key.
• Key Expiry:
  • Expiration for keys can be set with EX or PX during the SET operation.
• RESP Protocol:
  • Implements the Redis Serialization Protocol (RESP) for parsing and sending responses.
• Asynchronous:
  • Built with asyncio for handling multiple connections concurrently.
• Replication:
  • Implements master-replica communication using the REPLCONF and PSYNC protocols.
• Persistence:
  • Data persistence is supported for reliable storage between sessions.
• Concurrency:
  • Efficient handling of multiple clients using Go’s goroutines and synchronization primitives.

Installation

1. Clone the repository:

   git clone https://github.com/<your-username>/redis-clone.git

2. Navigate to the project directory:

   cd redis-clone

3. Run the server:

   python app/main.py
   

Usage

• Running the server:
  • PING: Test connectivity with PONG.
  • ECHO: Echo back the provided message.
  • SET: Store a key-value pair in the in-memory store.
    • Optional expiration using EX (seconds) or PX (milliseconds).
  • GET: Retrieve the value of a key.
  • REPLCONF: Handle replica configuration.
  • PSYNC: Synchronize data between master and replica.
