What is the impact of enabling auto-suspend on a Snowflake virtual warehouse?
When auto-suspend is enabled on a virtual warehouse, Snowflake automatically suspends (stops) the warehouse after it has been idle for the configured period of time. Once suspended, the warehouse stops consuming compute credits, thereby reducing costs, since Snowflake bills only for active compute usage. When new queries arrive, auto-resume (if enabled) restarts the warehouse automatically.
Auto-suspend does not change the warehouse size; scaling up or down is a separate configuration. The warehouse is not dropped---its metadata and settings remain intact. Costs may be reduced and made more efficient but are not guaranteed to ''stabilize month-to-month,'' as the bill still depends on actual usage and workload patterns.
