Data Versioning
Data versioning is a methodology for tracking changes to datasets over time, similar to how version control systems manage code. It involves creating snapshots or commits of data at different points, enabling reproducibility, auditability, and collaboration in data-driven projects. This is crucial for machine learning, data science, and analytics workflows where data evolves and needs to be managed systematically.
Developers should learn data versioning when working on projects involving large or frequently updated datasets, such as machine learning model training, data pipelines, or collaborative data analysis. It ensures that experiments can be reproduced, changes are traceable, and teams can roll back to previous data states if errors occur, reducing risks in production environments.
