Sophia is a transactional key-value and row storage library designed as a RAM-disk hybrid system. It provides an MVCC engine with optimistic concurrency control, serializable snapshot isolation, and append-only storage with multi-threaded compaction. The library targets embedded applications and secondary index construction, offering a minimalistic C API with FFI support.

History
Pavel Krivanek built Sophia as an open-source storage engine focusing on modern architectural choices for transactional key-value and row data. It gained attention for its unique region-based indexing and append-only design.
Development ceased after version v1.1, though its architecture influenced subsequent projects like Amelia and Monotone.
