Databricks enables many organizations to harness the power of data; but while Databricks enables collaboration across Data Scientists and Data Engineers, there is still opportunity to begin democratizing access to domain experts. Successfully achieving this requires a rethinking of the classic analytics user interfaces, towards interactive systems with highly collaborative visual interfaces. Current visualization and workflow tools are ill-suited to bringing the full team together. I will present Northstar, a novel system we developed for Interactive Data Exploration at MIT / Brown University, now commercialized by Einblick. I will explain why Northstar required us to completely rethink the analytics stack, from the interface to the “guts,” and highlight the techniques we developed to provide a truly novel user-interface which enables creating code optional analysis over Databricks, where all user personas can collaborate together very large datasets and use complex ML operations.
