A simple Bitcask-inspired key-value store written in Go.

Features

• Persistent key-value storage using append-only data files
• In-memory key directory for fast lookups
• Support for put, get, and delete operations
• File rollover when data files reach a configurable size
• Index rebuilding on startup for crash recovery
