A command-line tool and Python library that efficiently diffs rows between tables within or across SQL databases like PostgreSQL, MySQL, Snowflake, Oracle, and Trino. The open-source project was sunset by Datafold in May 2024 and is no longer actively maintained.
Use cases
- compare rows between two tables in different databases
- validate data parity after a database migration
- reconcile production and staging tables
- diff a Snowflake table against a Postgres table
- check data quality by finding changed rows between environments
- verify dbt model outputs row by row
When to choose
- you need fast row-level diffing across heterogeneous SQL databases
- you want a lightweight Python library or CLI for data reconciliation
- you're validating a data platform migration and don't need vendor support
When to avoid
- you need actively maintained software with bug fixes and new database support
- you want CI/CD data diffing with a UI - consider Datafold's commercial product instead
- you need long-term production support for a critical pipeline
