Most developers don't set out to "do data warehousing." They just want reliable tables, fast queries, and dashboards that don't break every Monday morning. But the old mental model-central warehouse, nightly ETL, everything modeled up-front-often collapses under today's realities: event streams, semi-structured data, AI workloads, and teams shipping changes daily.
