The most effective way for a data provider to validate secure view configurations is to create a data share for a test data consumer account. This method allows the provider to review and confirm that only the intended data is accessible in the secure view. Secure views are designed to mask or restrict data visibility, so creating a test share replicates the consumer's experience and ensures data security before sharing with actual consumers.

To improve the performance of compute-intensive queries, increasing the warehouse size (e.g., from Medium to Large or X-Large) provides more compute resources (CPU/memory), allowing Snowflake to process queries faster. This is the most direct and effective method for performance optimization.

System tags help enable data classification for governance, privacy, and compliance. For example, Snowflake uses system-defined tags like SNOWFLAKE.CORE.DATA_CLASSIFICATION to detect and label sensitive data (e.g., PII, financial info).
