Serverless compute quotas

Serverless quotas are a safety measure for serverless compute. Quotas are enforced on serverless compute for notebooks, jobs, Delta Live Tables, and for serverless SQL warehouses.

Quotas are measured in Databricks Units (DBUs) per hour. A DBU is a normalized unit of processing power on the Databricks platform used for measurement and pricing purposes. See the pricing page.

Quotas for serverless compute for notebooks, jobs, and Delta Live Tables

Serverless compute for notebooks, jobs, and Delta Live Tables includes a scale-up limit that imposes a maximum cost per workload per hour. Because this limit is enforced per workload, it does not prevent you from launching new jobs or notebooks using serverless compute.

For information about your account’s serverless scale-up limits, contact your Databricks account team.

Quotas for serverless SQL warehouses

Quotas for serverless SQL warehouses restrict the number of serverless compute resources a customer can have at a time. This quota is enforced at the regional level for all workspaces in your account.

When you reach your serverless quota in a region, workspaces cannot launch new serverless SQL warehouses. Reaching this limit does not terminate existing SQL warehouses in the region. However, if you reach the limit, Databricks prevents increasing the number of compute resources in the warehouse.

There are initial default quotas for accounts, but Databricks automatically proactively increases quotas based on your type of account and how you use Databricks. Databricks intends to prevent typical customers from reaching quota limits during normal usage.

Quotas are not intended as a capacity planning mechanism and are not a general purpose way to manage or limit spend.

Increase serverless quota

If necessary, you can request additional quota increases by emailing help@databricks.com. If you have a support plan, you can also make the request in your support portal. Your request for quota increase must include:

  • Set the subject line to "Serverless quota increase request"

  • One or more AWS regions

  • Your requested increase for the quota

  • Justification or reason for the quota increase
