Resource limits

The following tables list various numerical limits for Azure Databricks resources. For additional information about Azure Databricks resource limits, see each individual resource's overview documentation. For limits on Databricks Free Edition, see Databricks Free Edition limitations.

This page includes resource limits followed by API rate limits.

For limits where Fixed is No, you can request a limit increase through your Azure Databricks account team.
