Databricks Unity Catalog UAM Logs

Native query audit for Databricks Unity Catalog captures user data access within Unity Catalog and presents them in a universal format as Immuta audit logs. Immuta audits the activity of all Unity Catalog users and tables. Multiple access options are supported for audit:

  • Cluster queries with the following supported languages: SQL, Scala, Python, and R.
  • SQL warehouse queries


Databricks Unity Catalog integration with native query audit enabled

Best practices: Store audit logs

By default Immuta audit logs expire after 7 days. Export the universal audit model (UAM) logs to S3 or ADLS Gen 2, and store audit logs outside of Immuta in order to retain the audit logs long-term.

Audit frequency

Immuta collects audit records at the frequency configured when enabling the integration, which is between 1 and 24 hours. The frequency is a global setting based on integration type, so organizations with multiple Unity Catalog integrations will have the same audit frequency for all of them. The more frequent the audit records are ingested, the more current the audit records; however, there could be performance and cost impacts from the frequent jobs. Immuta will start a Databricks cluster to complete the audit ingest job if one is not already running.

To manually prompt the native query audit, click Load Audit Events on the Immuta audit page.

Audit schema

Each audit message from the Immuta platform will be a one-line JSON object containing the properties listed below.

Property Description Example

The Immuta name of the user who made the query. When the user is not registered with Immuta, the type, id, and name fields will be unknown. Taylor
actor.identityProvider The IAM the user is registered in. bim is the built-in Immuta IAM. When the user is not registered with Immuta, this field will be omitted. bim

auditPayload.query The command text of the query that was run in the integration. Immuta truncates the query text to the first 2048 characters. SELECT VERSION AS 'version' FROM 'sample-data'.'__immuta_version'

auditPayload.duration The time the query took in seconds. 0.557
auditPayload.errorCode The errorCode for the denied query. null if actionStatus is SUCCESS
auditPayload.technologyContext.type The technology the query was made in. DatabricksContext
auditPayload.technologyContext.clusterId The Unity Catalog cluster ID. null
auditPayload.technologyContext.workspaceId The Unity Catalog workspace ID. 8765531160949612
auditPayload.technologyContext.service Where in Unity Catalog the query was made. Possible values are SQL for SQL warehouses and NOTEBOOK for notebooks. SQL
auditPayload.technologyContext.warehouseId The Unity Catalog warehouse ID. 559483c6eac0359f
auditPayload.technologyContext.notebookId The Unity Catalog notebook ID. 869500255746458 The actor’s Unity Catalog account ID 52e863bc-ea7f-46a9-8e17-6aed7541832d
auditPayload.technologyContext.account.username The actor’s Unity Catalog username. The Unity Catalog host.
auditPayload.technologyContext.clientIp The IP address of the Spark cluster the request is coming from.
auditPayload.technologyContext.queryLanguage The queryLanguage corresponds to the programming language used: SQL, Python, Scala, or R. Audited JDBC queries will indicate that it came from JDBC here. python
auditPayload.objectsAccessed The Unity Catalog objects accessed. []
auditPayload.securityProfile.sensitivity.score The sensitivity score of the query. Classification must be configured for this field. INDETERMINATE
auditPayload.version The version of the audit event schema. 1
receivedTimestamp The timestamp of when the audit event was received and stored by Immuta. 2023-06-27T15:18:22.314Z

  • Enrichment of audit logs with Immuta entitlements information is not supported. While you will see these entitlements in the Databricks Spark audit logs, the following will not be in the native query audit for Unity Catalog:
    • Immuta policies information
    • User attributes
    • Groups
  • Immuta determines unauthorized events based on error messages within Unity Catalog records. When the error messages contain expected language, unauthorized events will be available for native query audit for Unity Catalog. In other cases, it is not possible to determine the cause of an error.
  • Audit for cluster queries do not support UNAUTHORIZED status. If a cluster query is unauthorized, it will show FAILURE.
  • Data source information will be provided when available:
    • For some queries, Databricks Unity Catalog does not report the target data source for the data access operation. In these cases the activity is audited, yet the audit record in Immuta will not include the target data source information.
    • Data source information is not available for unauthorized queries and events.
  • Column information from the query is not currently supported.
  • Immuta audit records include unregistered data sources and users; however, activity from them will not appear in any governance reports.
