SciDuck
A thin DuckDB layer for managing versioned scientific data.
Each variable is stored in its own table. Variables are associated with a hierarchical dataset schema (e.g. subject -> session -> trial) and can be saved at any level of that hierarchy. Multiple versions of each variable are supported natively.
All data -- including arrays -- is stored in queryable DuckDB types (LIST, nested LIST, JSON) so the database can be inspected with DBeaver or any DuckDB-compatible viewer.
Usage
from sciduckdb import SciDuck
duck = SciDuck("data.duckdb", dataset_schema=["subject", "session"])
duck.save("MyVar", data, subject="S01", session=1)
loaded = duck.load("MyVar", subject="S01", session=1)
Features
- Three save modes: DataFrame with schema columns (Mode A), single entry via kwargs (Mode B), or dict mapping tuples to values (Mode C)
- Automatic type inference: Maps Python/numpy types to DuckDB types
- Round-trip restoration: Metadata tracks original types for lossless load
- Version management: Automatic version numbering, duplicate hash detection
- Variable groups: Organize variables into named groups
- Schema validation: Validates dataset schema consistency across sessions
Note: all schema key values are coerced to strings before storage.
