Because suspending the virtual warehouse clears the cache, it is good practice to set an automatic suspend to around ten minutes for warehouses used for online queries, although warehouses used for batch processing can be suspended much sooner. This is often referred to asRemote Disk, and is currently implemented on either Amazon S3 or Microsoft Blob storage. Dont focus on warehouse size. Run from warm:Which meant disabling the result caching, and repeating the query. So lets go through them. Both Snowpipe and Snowflake Tasks can push error notifications to the cloud messaging services when errors are encountered.
