Virtual Warehouse sizing
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. You cannot change the size.
Before creating a Virtual Warehouse and setting the Virtual Warehouse size, learn about critical "Warehouse sizing requirements". If you misconfigure the size of your Virtual Warehouse, follow the procedure in "Correcting the Virtual Warehouse size" to delete and recreate the Virtual Warehouse.
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'|
- 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
Large warehouses with more executors can cache more data than small warehouses. Caching enhances performance.
