Hello @lizou1!

Yes, serverless compute has a quota, measured in Databricks Units (DBUs) per hour. For notebooks, jobs, or pipelines, there’s a built-in hourly spending upper limit.
To check your account’s serverless scale-up limits, you need to contact your Azure Databricks account team. You can also request a quota increase through the Azure Portal.
