DataHub November 2025 Release Notes
-
Canada Hub Cloud 01 and ANZ Local Hub Cloud 01 are now 4-byte UTF8 enabled for text/string fields. If your DataHub repository (where your golden records are stored) is hosted in these regions, your golden records now also support supplemental 4-byte characters and symbols. This update also improves matching performance and accuracy.
4-byte UTF8 support will be rolled out to all existing Hub clouds in the near future, as the existing 3-byte encoding is currently deprecated. (HUB-7355)noteImpact: This change affects your model size since text fields are now 4 bytes. Read Best practices for designing models for guidance on model size limitations.
-
Introduced metadata-based filtering for golden records, adding a new Source column and filter option to the Golden Record view. Users can now filter Golden Records by metadata attributes, allowing for more precise data exploration and analysis. The new Source filter dropdown provides options consistent with the Hub’s existing filter set, including Creating Source and Source Links. This addition aligns metadata filtering in the Golden Record experience with other Hub components, ensuring consistent filtering behavior across DataHub. (HUB-6686)
-
The max value when retrieving historical collections is now 50,000 across all clouds. This limit applies to the total accumulation of all collection entities fetched in historical queries. The Command Center UI now uses pagination to handle larger datasets gracefully within this threshold. The API will only return collections within the configured limit. This change ensures predictable query performance and prevents excessive memory consumption during large data retrieval operations. (HUB-6801)
-
We’ve improved the Command Center login experience by fully integrating it with Single Sign-On (SSO). Previously, users who logged in without certain account credentials would see a pop-up asking them to generate an access token. This extra step is no longer needed. With this update, Command Center now logs you in automatically through your organization’s SSO, providing a smoother and faster access experience. (HUB-6438)
-
The update ensures that Upsert and Delete operations on individual collection items correctly preserve the reference values of other items within the same collection field group. Mixed operations (e.g., Upsert/Delete combinations) now behave consistently, and performance has been verified at upper collection size limits. (HUB-6830)
-
Resolved an issue where the “Not Equal To” (!=) filter condition in Accelerated Query mode incorrectly included records containing null values. The expected behavior is for null values to be excluded from query results, matching the standard database filter logic. With this fix, the “Not Equal To” condition now properly ignores null values when Accelerated Query is enabled, providing consistent results across all field types and collection queries. (HUB-6605)
