KiloDB is a high-performance, Redis-compatible key-value database written in Rust. It implements the Redis protocol (RESP) and provides a subset of Redis commands, making it a lightweight alternative for applications that need Redis-like functionality.
- Strings: SET, GET, DEL, EXISTS, INCR, DECR, APPEND, STRLEN, MGET, MSET
- Hashes: HSET, HGET, HGETALL, HDEL, HEXISTS, HLEN, HKEYS, HVALS
- Lists: LPUSH, RPUSH, LPOP, RPOP, LLEN, LRANGE, LINDEX
- Sets: SADD, SREM, SMEMBERS, SISMEMBER, SCARD, SUNION, SINTER
- Key Management: KEYS, TYPE, TTL, EXPIRE, PERSIST, RENAME
- Single-threaded architecture for predictable performance
- In-memory storage with fast access patterns
- RESP protocol implementation for Redis client compatibility
- Efficient data structures optimized for Rust
- Redis Protocol (RESP) - Compatible with existing Redis clients
- TCP server listening on standard Redis port (6379)
- Connection handling with proper client lifecycle management
- Rust 1.70+ (Install Rust)

## 🛠️ Development
### Building
```bash
# Debug build
cargo build
# Release build
cargo build --release
# Run tests
cargo test
# Check code quality
cargo clippy- Add the command to
src/command/command_enum.rs - Implement execution logic in
src/command/executor/ - Add tests in
tests/directory
