How Delta Sharing Works

Delta Sharing is an open standard for secure data sharing. Having worked as a data solution architect with UK government departments over the years, one of the challenges that frequently cropped up was how to securely share data between departments. Delta Sharing would have been a straightforward answer… if it was available back then! In Databricks, Delta Sharing is seamless; baked into the UI and integrated with Unity Catalog providing overarching data governance. Of course you can use the open source version if you’re not using Databricks, anyone can just download the software and use it. It’s not as simple as using Databricks, but it is an alternative. You can download it at <a href="https://delta.io/sharing" rel="noopener ugc nofollow" target="_blank">https://delta.io/sharing</a>. I’m going to focus on using Delta Sharing through Databricks in this blog, specifically, secure sharing from Databricks to a 3rd party. This is known as open sharing. Databricks-to-Databricks sharing is also possible and also uses Delta Sharing behind the scenes. <a href="https://medium.com/@xsharpminor/how-delta-sharing-works-0df5063d3b7b">Read More</a>
