The databricks endpoint allows you to connect and manage Databricks data sources in Immuta.
Additional fields may be included in some responses you receive; however, these attributes are for internal purposes and are therefore undocumented.
Requirements
Databricks Spark integration
When exposing a table or view from an Immuta-enabled Databricks cluster, be sure that at least one of these traits is true:
The user exposing the tables has READ_METADATA and SELECT permissions on the target views/tables (specifically if Table ACLs are enabled).
The user exposing the tables is listed in the immuta.spark.acl.whitelist configuration on the target cluster.
The user exposing the tables is a Databricks workspace administrator.
Databricks Unity Catalog integration
When exposing a table from Databricks Unity Catalog, be sure the credentials used to register the data sources have the Databricks privileges listed below.
The following privileges on the parent catalogs and schemas of those tables:
USE SCHEMA on system.information_schema
Azure Databricks Unity Catalog limitation
Set all table-level ownership on your Unity Catalog data sources to an individual user or service principal instead of a Databricks group before proceeding. Otherwise, Immuta cannot apply data policies to the table in Unity Catalog. See the Azure Databricks Unity Catalog limitation for details.
Databricks workflow
Create a data source
POST /databricks/handler
Save the provided connection information as a data source.
