This document summarizes a presentation about building an open source, serverless data warehouse for MongoDB. It introduces the concept of data warehousing and analytics, then outlines the presentation agenda which includes discussing traditional vs new approaches to data warehousing, the data warehouse architecture and technology stack, and a hands-on session with the open source solution. The presentation hypothesis is that the approach to building data warehouses needs to change from traditional waterfall methods to a more agile approach using cloud services and providers of choice.
