Reconstructing a streaming session was a tedious and time consuming process that involved tracing all interactions (requests) between the Netflix app, our Content Delivery Network (CDN), and backend microservices. However, having a scalable stream processing platform doesn’t help much if you can’t store data in a cost efficient manner.
