Snowflake - Warehouse

In Snowflake, data is held in databases and any processing of data is done by something called a "warehouse."

Default three compute warehouses,

1. COMPUTE_WH owned by ACCOUNTADMIN.
2. SNOWFLAKE_LEARNING_WH owned by ACCOUNTADMIN
3. SYSTEM$STREAMLIT_NOTEBOOK_WH. That warehouse will be used by Snowflake to do any work required by streamlit apps and notebooks you create and run. You will not use this warehouse directly, only Snowflake will use it, on your behalf.

Scaling Up & Down : Changing the size of an existing warehouse is called scaling up or scaling down

Scaling In & Out : Warehouse is capable of scaling out in times of increased demand

Note : 

• Snowflake Warehouses do not hold data
• Opposite of scaling out is snapping back
• Cluster just means a "group" of servers.
• The number of servers in a warehouse is different, based on size (XS, S, M, etc)
• A cluster can hold multiple servers.
