At Jet.com, we have a lot of data. A LOT of data. We needed a way to safely, quickly, and relevantly process and explore all our data. Using F# and an event-based microservices architecture, we're able to do all this and more. In this talk, we'll cover how we handle processing events from 300+ microservices in to our data warehouse in real time, so that we can optimally react to our customers' wants and needs.
