Problem

We run a social media platform that pulls engagement events from the mobile apps in real time, alongside daily monetization files from ad partners and a handful of internal service pulls. Analysts need all of it queryable in the warehouse, but the team keeps redefining metrics like what counts as an active story viewer, so past numbers must stay rebuildable from each source's original, untouched records. Design the pipeline that lands these varied-cadence sources and shapes them for analytics.
