What is the interval used for checks when evaluating scaling decisions in Snowflake's multi-cluster warehouses?

• A. Every 15 seconds
• B. Every 1 minute
• C. Every 5 minutes
• D. Every 10 minutes

Answer: (B)

Scaling decisions for Snowflake's multi-cluster warehouses are evaluated on a fixed cadence to balance responsiveness with stability. Snowflake continuously monitors workload indicators such as concurrent queries and queue wait times across the clusters, and when thresholds are met, it may add more clusters. This decision process runs every minute, which is why the interval is one minute. If the load drops, it scales in after a short grace period to avoid rapid churn. Shorter intervals (like every 15 seconds) would cause unnecessary churn, while longer intervals (5 or 10 minutes) would delay reaction to spikes in demand.
