Article summary

Databricks is one of many delivery destinations that Bobsled supports. When delivering data from cloud object storage, Bobsled will turn the selected folders into tables in Databricks. Utilizing Databricks Delta Sharing ↗, Bobsled creates a Databricks-to-Databricks Delta Share in which the configured Databricks workspace(s) are granted access to create a read-only catalog from the share to query within their workspace.

Bobsled-managed Databricks

To learn how to configure a Databricks destination in Bobsled, please visit Bobsled-managed Databricks setup guide.


Bobsled requires the Databricks sharing identifier to grant your account access to the Delta share. A Metastore Admin (or another user with import create catalog and use provider) in the Databricks workspace that will consume the data must accept the Delta Share to make it available within the workspace. To learn more about the Databricks sharing identifier used within Bobsled please visit Account Access Identifiers in Databricks.

Bobsled supports advanced settings for data engineers who want to optimize specific table delivery options in Databricks


Bobsled supports the setting of the zOrder ↗ of a table in Databricks, resulting in optimized tables for expected query patterns.

  • To set up clustering, access the advanced settings icon on the right side of the table configuration screen.

  • Each table can have one cluster key configuration.

  • The order of the selected keys during setup is important, and Bobsled will respect that order.

Clustering can also be set using the tableSettings property on a share using the API ↗

If you are interested in using clustering to deliver optimized tables to your consumers but need assistance with the setup, please reach out to your account team.

Datatype override

Bobsled offers the capability to override a column's data type in your source schema with a different data type in the destination table.

If you wish to leverage data type overriding, please reach out to your account team.

Schema migration support

When new columns are added to tables or files, Bobsled efficiently handles schema migrations by adding new columns to existing tables without disrupting deliveries.

  • When new columns are introduced, they're seamlessly integrated, and any missing data in these columns is defaulted to null values.

    • This approach ensures that data loading continues smoothly, even with schema changes, preventing load failures and maintaining data integrity.

  • Our schema migration strategy is designed for flexibility and reliability during data structure evolution.

  • When columns aren't present in new files, the values for missing columns is set to null.
