RumDB

Blazing fast log-structured key-value storage based on Bitcask[1] whitepaper.

Features

• Low latency for reads and writes
• High throughput
• Easy to backup / restore
• Simple and easy to understand
• Store data much larger than the RAM

Roadmap

• Disk storage with hash map keydir structure
• GET/PUT/REMOVE operations
• Log files rotation
• Compaction and garbage collection
• Hint files for the faster startup time.
• Internal cache.
• Alternative storage implementations (e.g. tree-based to support range scans)
