Author: Inza Khan

Databricks’ Delta Sharing marks a watershed moment in the world of data sharing, addressing a long-standing industry challenge. Traditionally, enterprises have grappled with the constraints of vendor-tied data-sharing solutions, hindering seamless collaboration between organizations utilizing different platforms. This new open protocol shatters these limitations, offering a secure and real-time data-sharing avenue independent of the platform hosting the data.

Delta Sharing not only addresses the issue of proprietary lock-in but also tackles the challenge of sharing unstructured data. In a paradigm shift, businesses are increasingly inclined to share diverse data types such as images, videos, dashboards, and machine learning models. Unlike traditional data-sharing tools geared towards structured data, Delta Sharing is architected to seamlessly support unstructured data and express itself through Python, in addition to SQL. This flexibility ensures it caters to the diverse needs of data engineers, analysts, and scientists alike.

Delta Sharing becomes more than just a solution to isolated data-sharing challenges. It extends the applicability of the Lakehouse architecture rapidly gaining traction in organizations today. This extension means that Delta Sharing not only facilitates an open, simple, and collaborative approach to data and AI within organizations but also acts as a bridge between different entities. It enables organizations to share and collaborate on data seamlessly, fostering innovation and efficiency in an interconnected world.

What is Delta Sharing?

The shortcomings of traditional data-sharing methods in data management have long hindered seamless collaboration and robust security measures. Methods like FTP, emailing copies of flat files or utilizing APIs often fall short in scalability, demand manual infrastructure upkeep, and pose challenges for real-time access, making collaboration a daunting task. Security concerns further compound these issues, especially when dealing with large datasets. This is where Databricks Delta Sharing enters the chat. It is a revolutionary open protocol that redefines the dynamics of collaborative data sharing while reinforcing all security measures.

Developed by Databricks, Delta Sharing is not just a solution; it’s a paradigm shift in how data is shared and accessed across organizations. At its core, Delta Sharing eliminates the need for duplicating data or imposing access restrictions. It acts as a bridge, fostering collaboration by providing a secure and real-time data-sharing avenue. Its significance is underscored by the inclusion of third-party tools that seamlessly manage, govern, and audit shared data, ensuring a comprehensive solution for organizations seeking efficiency in data collaboration.

Delta Sharing’s Comprehensive Approach

The Delta Sharing project doesn’t merely offer a solution; it aims to address the fundamental challenges in data movement, scalability, and security and governance complexities. The open protocol defines a structured approach to the secure, real-time exchange of large datasets among both internal and external stakeholders. The open-source REST protocol, a cornerstone of Delta Sharing, ensures a secure and consistent method to access data stored on popular platforms such as S3, ADLS, or GCS.

The protocol specification introduces critical concepts such as shares, schemas, tables, recipients, and sharing servers. Shares logically group schemas, allowing them to be shared with one or more recipients. Schemas, in turn, group tables, with each table representing a Delta Lake table or view. Recipients are the principals granted secure access to shared tables. This meticulous structuring provides an opening to implement rigorous data governance controls that are crucial in today’s data-centric landscape.

Delta Sharing Reference Server: A Hub for Secure Implementation

The Delta Sharing Reference Server is the starting point in the Delta Sharing ecosystem. It is a simple development server that implements the Delta Sharing Protocol. The reference server allows anyone to expand upon it and create custom implementations of the Delta Sharing Protocol on their own data. A major advantage of using Databricks is getting access to the powerful Unity Catalog feature for data governance when using the platform. Databricks brings the reference server to the next level by providing first-party support and a full-fledged Delta Sharing implementation out of the box. This reference implementation acts as a foundation to facilitate the adoption of the Delta Sharing protocol across the web.

Connectors for Apache Spark

To enhance the accessibility of Delta Sharing, pre-built connectors have been crafted for Apache Spark. The Apache Spark Connector provides versatility, enabling the loading of shared tables through SQL, Python (as PySpark), Java Scala, and R. The Python Connector, specifically, empowers users by allowing them to load shared tables directly as pandas DataFrames into their project, facilitating easy integration into nearly any data-science workflow. This flexibility ensures that technical experts, regardless of their preferred workflow, can seamlessly incorporate Delta Sharing into their data management practices.
