Warehouse selection strategies in Snowflake - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is a warehouse in Snowflake?

A warehouse in Snowflake is a cluster of compute resources used to perform data processing tasks like queries and loading data.

beginner

Why choose a larger warehouse size in Snowflake?

A larger warehouse size provides more compute power, which can speed up query processing but costs more credits.

What is the benefit of using multi-cluster warehouses?

Multi-cluster warehouses automatically add or remove clusters to handle varying workloads, improving concurrency without manual intervention.

beginner

How does auto-suspend help in warehouse selection?

Auto-suspend pauses the warehouse after inactivity, saving costs by not running compute resources when not needed.

intermediate

What factors influence the choice of warehouse for a query?

Factors include query complexity, concurrency needs, cost considerations, and workload patterns.

What does a larger Snowflake warehouse size provide?

A More compute power

B More storage space

C Longer query times

D Lower cost

A larger warehouse size means more compute resources, which speeds up queries.

What is the main advantage of multi-cluster warehouses?

A Slower query processing

B Reduced storage costs

C Manual cluster management

D Automatic scaling for concurrency

Multi-cluster warehouses add or remove clusters automatically to handle many users.

What does auto-suspend do in Snowflake warehouses?

A Increases warehouse size

B Deletes warehouse data

C Pauses warehouse after inactivity

D Starts warehouse automatically

Auto-suspend saves cost by pausing compute when not in use.

Which factor is NOT important when selecting a warehouse?

A Color of the warehouse icon

B Concurrency needs

C Cost considerations

D Query complexity

The icon color has no impact on warehouse performance or cost.

What happens if you choose a warehouse too small for your workload?

A Costs will be higher

B Queries may run slower

C Warehouse will auto-scale to larger size

D Data will be lost

A small warehouse may not have enough compute power, causing slower queries.

Explain how Snowflake warehouse size and multi-cluster options affect query performance and cost.

Think about how compute resources and concurrency affect query speed and billing.

Describe the role of auto-suspend and auto-resume in warehouse cost management.

Consider how pausing and starting compute resources affects billing.
