How to size a Virtual Warehouse
When you create a Virtual Warehouse, you need to carefully set the size of your Virtual Warehouse. The size of the Virtual Warehouse you select during Virtual Warehouse creation determines the number of executors and concurrent queries the Virtual Warehouse can run.
When you create a Virtual Warehouse, you select one of the following Virtual Warehouse sizes:
|Virtual Warehouse Size||Number of Executors|
|Custom||Enter a value between '1' and '100'|
|use workload aware autoscaling||Set your smallest and largest executor group sizes. Custom sets can be added with executor group sizes inside this range (3 Maximum). All group sizes must be within 1 and 100.|
- The number of executors you typically use for clusters in an on-premises deployment.
- The complexity of your queries and the size of the data sets that they access.
Large warehouses with more executors can cache more data than small warehouses. Caching enhances performance.
