Module Issue Reported in


ONE-53206: RDM enrichment feature does not function.


Data Stories

This consolidated update aims to improve your experience with Data Stories by fixing bugs, providing enhancements to existing functionalities, and adding minor improvements to the user interface.

Visualizations Improvements

  • The name of the source catalog item or Data Quality (DQ) result is now prominently displayed right above the raw data in the table in Data View. This gives you a clearer reference to your data source.

  • Visualization names are now displayed directly in the pop-up editor when editing a visualization from the Report Builder, whether it’s a dashboard or story.

  • We improved the Cumulative Sum function, ensuring it seamlessly integrates with Multiseries charts. When using this feature in the visualization builder, you no longer encounter validation errors.

  • We renamed the Top N feature to Top/Bottom Values and added a tooltip to explain how the functionality affects your visualization results.

  • We improved the formatting functionality of numeric values in your visualizations.

UI Improvements

  • The Visualization Builder is now better adjusted for smaller screen resolutions. In addition, switching between data table and visualization is more intuitive (using icons instead of text).

  • Updated empty state for no filter results: Improved messaging for cases when no data is displayed due to filters applied.

  • Improved Select/Create collection modal: When creating a new visualization, it’s now easier to select between existing collections or create a new one directly from the modal.

  • Create buttons on Home and Report screens: When you select Create on the Home or Report screen, you can no longer create individual visualizations, only dashboards or stories.

  • Renamed Add transition to side option: The Add transition to side option is renamed to Slide-in horizontally to better reflect its functionality. This option allows slides to move horizontally in Presentation or View mode, offering an alternative to the default vertical transition.


REST API Response Improved

The master_id attribute is now included in the response from instance write endpoints. This functionality is configured in the file (see MDM Server Application Properties, section MDM Features).

Rate Limiter for REST Requests

We added a rate limiter that allows controlling the frequency of REST requests by setting rate limits based on URI and HTTP method. If the limits are exceeded, a 429 Too Many Requests HTTP response status code will be returned to prevent server overload. To learn more, see Rate Limiter.

New Prometheus Metrics

We have introduced new Prometheus metrics to monitor various aspects of user activity, data volumes, data changes, and data models. These metrics ensure transparent monitoring and can be useful for debugging and understanding the MDM environment.

MDM Upgrade Notes

To determine your upgrade path, see MDM Upgrade Procedure and MDM 14.5.3 Upgrade Notes.


REST API Improvements

When retrieving records using RDM REST API, you can now define business dates. If the businessDate parameter in modeSetup is set to null, the response now contains only records that are currently valid (as defined in the business date columns for the table). Previously, having businessDate set to null returned all records.

You can also use businessDate to retrieve records that were valid at a particular point. If you need to retrieve all records, use ignoreBusinessDates instead. For details, see RDM REST API, section Get records with advanced filtering.

In addition, you can limit how many records are returned in each request by setting the properties and These define the default limit for each request as well as the maximum number of records that can be obtained in a single request, respectively. To learn more, see RDM Application Properties, section RDM properties.

Two additional fixes were introduced:

  • Records can now be filtered by a DATE datatype field as expected.

  • Boolean and numeric data is correctly represented in JSON datatypes (without quotes).

Changes to Publish Action in Create and Edit Dialog

The Publish action in Create and Edit dialog, which lets you publish changes immediately after creating or editing a record, is now shown only on entities that have no workflow defined.

In addition, the Publish and Save options are now displayed next to each other. Previously, to access Save, you first had to open the actions menu.

New Prometheus Metrics

We have introduced new Prometheus metrics to monitor various aspects of user activity, data volumes, data changes, and data models. These metrics ensure transparent monitoring and can be useful for debugging and understanding the RDM environment.
