100 Cost Optimization Techniques in Snowflake

Explore how Snowflake virtual warehouses, including 64-node setups, affect query speed and cost through hands-on experiments, comparing multi-cluster, manually resized standard, and Snowpark-optimized warehouses, plus economy scaling policies.

Discover how larger Snowflake warehouses can lower overall costs by shortening query time, yielding a breakeven point where faster queries offset higher node charges.

Learn to auto-suspend any warehouse after one minute of activity, enable auto resume, and cut idle warehouse costs.

Resuming a warehouse costs at least one minute, even after brief use; billing then runs per second while active, so set auto suspend to one minute.

X-small Snowflake warehouses can be powerful enough to start, offering eight vCPUs, 16 GB RAM, and 200 GB SSD per node, with a two-node distributed cluster that scales as needed.

Resize warehouses manually between fixed t-shirt sizes; bigger sizes speed complex queries. A single query runs on one warehouse; multi-cluster setups require the same size across all.

Enable true concurrency by using multi-cluster warehouses that auto scale across identical-size clusters, support multiple users, and scale between 1 and 10 clusters, which do not improve complex queries.

Set the minimum cluster count of multi-cluster warehouses to one to avoid overprovisioning and unnecessary costs, while allowing autoscale to meet varying user requests.

Cancel long-running queries in Snowflake only for your own queries via the SQL worksheet cancel button, the query history, or the Cancel Query system function with the query ID.

Start with the smallest warehouse, extra small, and set auto suspend to one minute; monitor usage, cancel queries, drop unused expensive warehouses, and increase size only when needed for performance.

Consolidate all warehouses to reduce idle credits and optimize workload placement. Group similar workloads, including ETLs, interactive, and dashboards, into shared warehouses to balance max concurrency and minimize auto-suspend overhead.
