Datafold has announced it will no longer support or develop its open-source data-diff tool as of May 17, 2024, instead encouraging users to try Datafold Cloud for database diffing. The company was founded to help data engineers ship faster without sacrificing quality, addressing challenges like the lengthy testing and validation processes in data engineering. A pivotal experience at Lyft highlighted the need for better tools to prevent errors from affecting downstream data pipelines. Datafold emphasizes the importance of data diff and data lineage technologies to provide visibility into the impact of code changes on datasets and downstream applications, advocating for deployment testing during the development process. Over the past three years, Datafold's automated pre-production testing helped data teams identify regressions and align with data consumers, with many users interested in early-stage testing, reflecting the shift-left trend in software engineering. Although Datafold open-sourced the data-diff tool to support efficient data comparison, they recognize that maintaining high data quality requires a comprehensive workflow beyond just data comparison.
