Global media ingest

Design a globally-distributed media ingest system for a short-video app where creators worldwide upload from mobile and the uploaded video must become available to a global audience fast, regardless of where the creator is. A creator in Jakarta uploading to a US-region origin gets terrible throughput and slow first-publish. You must minimize upload latency and first-byte-to-published time while keeping a coherent global view of content. Design the edge ingest, the path from edge to processing, and the consistency model.
