Unless you are bulk loading a large number of files concurrently (i.e. In a standard policy, if the system detects there is one more query than the current number of clusters can handle, it will start a new cluster, and then shuts down a cluster after 2-3 consecutive successful checks in 1 minute intervals to determine if the load on the least loaded cluster can be redistributed to the other clusters without spinning up the cluster again. Since we are not getting exact size of node/server/cluster of snowflake, can you please suggest us what should be the warehouse size we should choose. As one of the core aspects of Snowflake, it is important to understand how these resources are billed.

The Snowflake web interface also has a nice visual representation of this function (under the Warehouse tab): For more details on this chart, see our online documentation. been billed for that period. Snowflake uses double-precision (64 bit) IEEE 754 floating-point numbers. Read this deep-dive into understanding query profiling. When scaling down, compute resources and the cache associated with those resources are dropped, which can impact performance due to no longer having the full extent of the cache available. 2. Unless there are specific requirements for the warehouse to be running in maximized mode (all clusters in a warehouse always running) or there are concerns about high-availability of the warehouse, the recommendation is to set minimum clusters to 1 and maximum clusters to 8 while being mindful of costs to configure the warehouse to run in auto-scale mode. charged for both the new warehouse and the old warehouse while the old warehouse is quiesced.

You might want to consider disabling auto-suspend for a warehouse if: You have a heavy, steady workload for the warehouse. Snowflake virtual warehouses come in what they refer to as T-shirt sizes, starting with X-small for the smallest and going all the way up to 4X-Large, as 5X and 6X are in private preview. This topic provides general guidelines and best practices for using virtual warehouses in Snowflake to process queries. Understanding Your Snowflake Utilization, Part 1: Warehouse Profiling. additional resources, regardless of the number of queries being processed concurrently.
