Sophia is advanced Open-Source Embeddable Transactional Key-Value Storage. Can be used in form of shared library or integrated within a project. Written in C with zero dependencies.

RAM-Disk Hybrid

Sophia has unique hybrid architecture that was specifically designed to efficiently store data using the combinations of Disk, Flash and RAM. Sophia allows to distinct Hot (read/write-intensive) and Cold data.

Supported storage modes are:

• Disk Storage Disk or Flash is the primary storage. Write requests are cached in RAM for futher compaction.
• Anti-Caching RAM becomes the primary storage for Hot data. Cold data stored on Disk or Flash.
• Persistent Caching Secondary storage used as an LRU cache for Hot data stored in RAM or Flash. Cold and Hot data persisted on Disk or Flash.
• Persistent RAM Storage RAM is the primary storage. Data continiously persisted on Disk or Flash.

The MVCC Append-Only data storage engine was created as a result of research and reconsideration primary algorithmic constraints of Log-file based data structures. It is Write and Range Scan optimized.
