A better Snowflake model leverages these features instead of fighting them. outlines five key practices for preparing data for
For BI workloads, star schemas generally outperform fully normalized designs. Denormalize for query speed and accept some storage redundancy—columnar storage keeps it manageable.
Because storage and compute are decoupled, you can:
