CloudVerse BI should not crush the orders primary with ad-hoc scans.
See it live — copy this example
Use AWS/Azure/GCP free tier or local Docker/Kind. Sketches and YAML are meant to be typed and adapted.
# layout
# OLTP SQL (orders) → CDC/ETL → warehouse
# object lake for raw events
# BI reads warehouse, not primaryWhat happened?
- Data contracts between producers and consumers.
- PII classification.
- Cost controls on warehouse scans.
Practice next
- Draw OLTP vs warehouse.
- Add one ETL job.
- Lock BI off primary.
- Columnar warehouse table.
- Mask PII in lake.
Remember
Separate OLTP/analytics. Contracts. PII + cost.
CloudVerse data estate
BI on warehouse only.
Outcome: Checkout p95 stable during reports.
