Explore large-scale data validation techniques using Spark and Dask in this informative PyCon US talk. Discover how data validation ensures the reliability of data pipelines and preserves workflow integrity. Learn about the differences between single-machine and distributed computing settings for data validation, and understand which validations become more computationally expensive in Spark and Dask. Examine the need for applying different validations on various data partitions and how to achieve this by combining different frameworks. Follow a fictitious case study that demonstrates the data validation journey, starting with small-scale Pandas-based validations using Pandera and Great Expectations, and progressing to distributed settings. Gain insights into the challenges of transitioning to large-scale data validation and learn how to reuse Pandas-based validations on Spark and Dask using Fugue. This 26-minute talk provides valuable knowledge for data scientists and engineers working with increasing data volumes and complex validation requirements.
