Release 9.0.27.1¶

Support for Standardized Outgoing Request Metrics in Grafana Dashboards¶

Added Grafana panels to monitor outgoing HTTP requests with metrics for total count, error rate, and response time. Includes detailed time series by status code, method, and URL for improved visibility and debugging.

Periodic Policy Cache Refresh¶

Introduced periodic policy cache refresh to ensure the in-memory cache stays in sync with the database when policy delta is enabled. The refresh interval is configurable via RANGER_ADMIN_POLICY_CACHE_REFRESH_INTERVAL_MINUTES.

Fixed User Deletion Issue¶

Resolved an issue where user deletion would fail if the user was part of a policy linked to a service that had been renamed after the policy was originally created.

Implemented Validations For Revoke Role API¶

The Revoke Role API has been enhanced to include proper validations. It now returns appropriate response codes when attempting to revoke a non-existent user, group, or role, improving error handling and API clarity.

Enhanced Dremio Connector Stability and Error Handling¶

• Socket Timeout Handling: Implemented socket timeout handling for REST calls to prevent indefinite hanging.
• ResourceLoader Fixes: Resolved issues in ResourceLoader to maintain data integrity in RocksDB during exception scenarios.
• Improved Error Recovery: Enhanced overall stability and error recovery mechanisms for the Dremio connector.

Enhanced Unity Catalog Permission Support¶

Implemented comprehensive permission support for Unity Catalog, including the addition of manage permission and new resource materialized view capabilities with associated permissions.

By default, the connector excludes all newly supported permissions and takes no action on them until they are explicitly included using the Inclusion Property. For more information, see Manage Permissions List.

Datatype Masking Improvements in Unity Catalog¶

Resolved inconsistencies in column masking functionality for Boolean and BigInt data types across different user sessions. Enhanced the connector to support masking operations for all available data types in Unity Catalog.

For details on supported datatypes and their masking behavior, see Datatypes Masking Mapping.

ABAC Policy Revaluation Enhancement¶

Implemented revaluation of ABAC policies when Principal Attributes are updated, ensuring consistent policy enforcement and attribute-based access control.

Databricks Unity Catalog SCIM API Throttling Management¶

Building upon previous throttling handling improvements, introduced configurable properties for DBX SCIM API throttling management:

• Configurable retry interval following API throttling
• Adjustable maximum retry attempts for throttled API calls

Decimal Data Type Masking Enhancement¶

Resolved issues with column masking functionality for specific decimal data types, particularly Decimal(15,2). The solution now supports masking operations for all decimal data type variations.

ChangeLog Processing Optimization¶

Addressed and resolved an issue with duplicate ChangeLog entries in the processing queue, which was causing delays in principal action execution and policy application on the service end.
