Snowflake - Build and Architect Data Pipelines Using AWS - More about Views in Snowflake

The video tutorial covers the advantages of materialized views, which improve query performance by persisting data on disk and being automatically maintained. It provides guidelines on when to choose materialized views over normal views, based on query frequency and resource consumption. Secure views are discussed in the context of data privacy, emphasizing their use for limiting access to sensitive data. The tutorial concludes with a recommendation to consult official documentation for further learning.

What is one of the main benefits of using materialized views in Snowflake?

• They reduce storage costs.

• They automatically generate reports.

• They improve query performance by storing results on disk.

• They allow for real-time data streaming.

When should you opt for a materialized view over a normal view?

• When you need to limit access to sensitive data.

• When query results are rarely used.

• When query results change frequently.

• When the query is resource-intensive and results are used often.

Which scenario is best suited for using a normal view?

• When query results are stable and frequently accessed.

• When you need to improve query performance.

• When query results change often and are not frequently used.

• When data privacy is a concern.

What is a key reason to create a secure view?

• To ensure data privacy and restrict access to sensitive data.

• To simplify code reusability.

• To enhance query performance.

• To reduce storage requirements.

Why should secure views not be used for query convenience?

• They are more expensive to maintain.

• They bypass certain optimization techniques, affecting performance.

• They require additional storage space.

• They are difficult to implement.
