This repository contains a Go implementation of the Bitcask key-value store as described in the Riak Bitcask paper. Bitcask is a high-performance, persistent key-value storage system optimized for fast reads and writes. It is designed to handle large datasets with low-latency access, making it suitable for applications that require efficient data storage and retrieval.

- High Performance: Optimized for fast read and write operations.
- Persistence: Ensures data durability by storing data on disk.
- Concurrency Control: Utilizes read-write locks to manage concurrent access.
- Data Integrity: Implements mechanisms to maintain data consistency.
- Extensible Options: Supports configurable options for customization.
The Bitcask implementation follows the architecture outlined in the Bitcask paper, focusing on simplicity and performance. Key components include:
- Data Files: Stores key-value pairs on disk.
- Indexing Mechanism: Maintains an in-memory index to map keys to their locations in data files.
- Concurrency Management: Uses synchronization primitives to handle concurrent operations safely.
