If the load is low for 15 minutes, Databricks downscales the SQL warehouse. In addition, an warehouse is always upscaled if a query waits for 5 minutes in the queue. Otherwise, Databricks adds 3 clusters plus 1 cluster for every additional 15 minutes of expected query load. Upscaling of clusters per warehouse is based on query throughput, the rate of incoming queries, and the queue size.ĭatabricks adds clusters based on the time it would take to process all currently running queries, all queued queries, and the incoming queries expected in the next two minutes. You can also create a SQL warehouse with the Databricks Terraform provider and databricks_sql_endpoint.ĭatabricks limits the number of queries on a cluster assigned to a SQL warehouse based on the cost to compute their results. Your SQL warehouse is now created and started. You can then configure warehouse permissions if you’d like. See What are the available warehouse types?. To learn how Databricks adds clusters to and removes clusters from a warehouse, see Queueing and autoscaling. To handle more concurrent users for a given query, increase the cluster count. The default is a minimum of one and maximum of one cluster. Scaling sets the minimum and maximum number of clusters over which queries sent to the warehouse are distributed. Note that you can create a serverless SQL warehouse using the SQL warehouses API, in which case you can set the Auto Stop value as low as 1 minute. The minimum is 5 minutes when you use the UI. Serverless SQL warehouses: The default is 10 minutes, which is recommended for typical use. Pro and classic SQL warehouses: The default is 45 minutes, which is recommended for typical use. Idle SQL warehouses continue to accumulate DBU and cloud instance charges until they are stopped. For details, see Cluster size.Īuto Stop determines whether the warehouse stops if it’s idle for the specified number of minutes. To reduce query latency, increase the size. To create a SQL warehouse using the web UI:Īccept the default warehouse settings or edit them.Ĭluster Size represents the number of cluster workers and size of compute resources available to run your queries and dashboards. If your workload or environment requires different capabilities, you can override those defaults. You can create a SQL warehouse using the New SQL Warehouse page in the web UI or using the SQL Warehouse API.įor more information about managing serverless SQL warehouses with the API, see Using Warehouses API with serverless SQL warehouses.īy accepting all the defaults on the New SQL Warehouse page, you can create an efficient and high-performing SQL warehouse quickly and easily.
