| Pitfall | Why It Hurts | Better Approach | | :--- | :--- | :--- | | | Excessive joins explode query compilation time. | Flatten JSON or use VARIANT types; join only dimension to fact. | | Using SELECT * | Snowflake reads all micro-partitions. | Explicit column projection reduces I/O. | | Unique constraints | Snowflake does not enforce them (except for PRIMARY KEY as metadata). | Use QUALIFY ROW_NUMBER() = 1 or stream processing. | | VARIANT vs. Relational | Deep nesting slows analytic queries. | Parse VARIANT into columns at ingestion time for reporting. | | Use QUALIFY ROW_NUMBER() = 1 or stream processing

Snowflake automatically manages how data is physically stored.
