Interview Prompt
A retailer's checkout flow uses Snowflake as the application's primary database. Point lookups by primary key take seconds, single-row updates rewrite full Parquet files, and the multi-row checkout transaction has no native ACID support. Customers see timeouts. Apply the section's operational-database framing and replace the warehouse-as-OLTP store with the shape the section names for sub-millisecond ACID writes.
