- Worth noticing
- The first case follows a missing-revenue incident from serving back through the warehouse, transformation, and ingestion layers.
Field notes
The first investigation asks readers to work backward through serving, warehouse, transformation, and ingestion to find why revenue vanished from reports. The planned season follows one company as it grows, with later case descriptions involving a sharply slower job, a cloud invoice, and duplicate customer records. The page says episodes include sources for their numbers; its SQL, PySpark, and AI practice modules are marked as in build.
