Identity resolution library built on Splink and DuckDB.
Project description
SPAN
span_data is an identity resolution library built on Splink and DuckDB. It
links records that refer to the same entity and produces a unified ID graph.
Early release. This package is under active development, and the public API and import paths may change between releases. We expect to follow semantic versioning more strictly after a 1.0 stable baseline; until then, treat upgrades as potentially breaking. Pin a specific version in production and review span_data/packaging_info/CHANGELOG.md before upgrading.
Core Features
- Ingest source data from pandas DataFrames, CSV files, and Snowflake tables or views.
- Clean and normalize source fields.
- Resolve entities into profile graphs with Splink-based matching.
- Export graph results to DataFrames, CSV, Parquet, DuckDB relations, and Snowflake.
- Apply manual override workflows for merge, split, and assign operations.
Python Support
This package currently supports Python >=3.11,<3.12.
