Data quality management for SQL- and Spark- accesssible data.

✔ An open-source, CLI tool and Python library for data reliability
✔ Compatible with Soda Checks Language (SodaCL) and Soda Cloud
✔ Enables data quality testing both in and out of your pipeline, for data observability, and for data monitoring
✔ Integrated to allow a Soda scan in a data pipeline, or programmatic scans on a time-based schedule

Soda Core is a free, open-source, command-line tool that enables you to use the Soda Checks Language to turn user-defined input into aggregated SQL queries.

When it runs a scan on a dataset, Soda Core executes the checks to find invalid, missing, or unexpected data. When your Soda Checks fail, they surface the data that you defined as “bad”.

Soda Core currently supports connections to several data sources. See Compatibility for a complete list.

Requirements

• Python 3.8 or greater
• Pip 21.0 or greater

1. To get started, use the install command, replacing soda-core-postgres with the package that matches your data source. See Install Soda Core for a complete list.
   pip install soda-core-postgres
