Redis-like In-Memory Store in Java

This project is a simple Redis-like in-memory key-value store implemented in Java. This project is made to understand how redis works, networking, concurrency and persistence(not implementation yet).It supports basic Redis commands such as SET, GET, INCR, LPUSH, RPUSH, LPOP, RPOP, LLEN, and LRANGE. The project uses Java NIO for non-blocking I/O operations, making it suitable for handling multiple client connections concurrently.

Features

• In-Memory Storage: Stores key-value pairs in memory with optional expiration.
• Basic Redis Commands: Supports a subset of Redis commands for string and list operations.
• Non-Blocking I/O: Uses Java NIO for handling multiple client connections efficiently.
• Expiration: Supports setting expiration time for keys.
• List Operations: Supports operations on lists such as LPUSH, RPUSH, LPOP, RPOP, LLEN, and LRANGE.

Prerequisites

• Java Development Kit (JDK) 21
• Maven (for building the project)
