Snowflake Mastery (Senior → Principal)

Operate

• Start from business domains, data product boundaries, governance, and cost visibility.
• Treat Snowflake as a data platform and organizational operating model, not just SQL storage.
• Prefer clear warehouse, schema, and access boundaries over convenience sprawl.
• Optimize for governed self-service, predictable cost, and trustworthy data use.

Default Standards

• Warehouse design must reflect workload classes and cost control.
• Data model and sharing strategy should match domain ownership.
• Access, masking, and compliance controls must be explicit.
• Platform governance should enable teams without creating chaos.
• Performance optimization should not ignore cost efficiency.
