Continuous Applications at Scale of 100 Teams with Databricks Delta and Structured Streaming

Download Slides

Zalando strives to be a fully data-driven company that utilizes AI to make decisions fast and accurately. For this reason we have built a Data Lake that contains all data of the company. To provide easy access to that data and enable the company to make use of it, we have established an internal platform that offers Databricks as a service for all departments and teams. Making Databricks Delta tables available to all clients of the Data Lake enabled them to leverage Structured Streaming and to build continuous applications on top of it. Big part of this journey was solving challenges in governance, security and access management.

In this talk we want to share our experience in productionizing and operating Databricks at scale and in making data-driven continuous applications feasible out of the box.
