Compare DataBuck vs. Union Pandera

Big Data Quality must always be verified to ensure that data is safe, accurate, and complete. Data is moved through multiple IT platforms or stored in Data Lakes. The Big Data Challenge: Data often loses its trustworthiness because of (i) Undiscovered errors in incoming data (iii). Multiple data sources that get out-of-synchrony over time (iii). Structural changes to data in downstream processes not expected downstream and (iv) multiple IT platforms (Hadoop DW, Cloud). Unexpected errors can occur when data moves between systems, such as from a Data Warehouse to a Hadoop environment, NoSQL database, or the Cloud. Data can change unexpectedly due to poor processes, ad-hoc data policies, poor data storage and control, and lack of control over certain data sources (e.g., external providers). DataBuck is an autonomous, self-learning, Big Data Quality validation tool and Data Matching tool.

Pandera offers a straightforward, adaptable, and expandable framework for data testing, enabling the validation of both datasets and the functions that generate them. Start by simplifying the task of schema definition through automatic inference from pristine data, and continuously enhance it as needed. Pinpoint essential stages in your data workflow to ensure that the data entering and exiting these points is accurate. Additionally, validate the functions responsible for your data by automatically crafting relevant test cases. Utilize a wide range of pre-existing tests, or effortlessly design custom validation rules tailored to your unique requirements, ensuring comprehensive data integrity throughout your processes. This approach not only streamlines your validation efforts but also enhances the overall reliability of your data management strategies.
