"Premium Automated Serverless Compute - Promo DBU" expenses arise from what, how can I disable it, and why are the costs so high?

Hello everyone!

Currently, I found that over 90% of the cost from "Premium Automated Serverless Compute - Promo DBU" is due to Databricks Materialized View working with Job + SQL Warehouse Serverless. I have now resolved the issue by discontinuing the use of Materialized View and reverting to using a regular Delta Table. I noticed that the associated cost has almost entirely disappeared.

@Pratya Thanwatthanakit - Thanks for the question and using MS Q&A platform.

By default, new workspaces have serverless SQL warehouses enabled in supported regions. See Enable serverless SQL warehouses.
