Ataccama Security Advisories

Known Issues

This section lists issues we are currently aware of which are considered significant, and which could impact the functionality of your build. We highly recommend reviewing this section before every upgrade.
Module Issue To be resolved in


ONE-54687: A change made to an instance of a child (embedded) entity does not trigger the parent entity to be included on the Unpublished tab of the entity listing screen even though it puts the parent entity in Draft state.

This occurs on all entity types that include an Unpublished tab (for example, terms, rules, and monitoring projects).



ONE-56889: After the history plugin refactoring, backward compatibility is broken and previously defined plugin settings are ignored.



ONE-54647: MDM fails to start when configured to use Amazon SQS. Contact Ataccama support for further assistance.

14.5.3, 15.3.0


Improvements to Rules

Version 15.2.0 brings a simplified and more intuitive way of creating DQ rules and applying them to attributes.

Quick Rule Creation Flow

You can now create a rule directly in Data Catalog and test it on sample data, which is particularly useful if you spot an issue while browsing the catalog.

The rules created this way use a simplified rule creation flow that contains only the most commonly used options for creating rules. The rule template is prefilled with input and test data from the catalog item, and the rule is automatically applied to the attribute it was created from.

You can always add advanced options, such as variables, later on in the rule library.

In addition to Data Catalog, this option is also available in Monitoring Projects and ONE Data.

For more information, see Create DQ Evaluation Rule.

Create rule from profile

Rule Suggestions

When applying a rule, ONE can help you pick the rules that are most suited to evaluate your data.

You can use two types of rule suggestions: either select Check for rule suggestions to identify patterns and irregularities in the profiling statistics and suggest rules based on these, or use Detect rules for AI-generated rule suggestions.

AI-based rule suggestions are an experimental feature only available in Ataccama Cloud Essential, Professional, and Enterprise tier deployments.

If a suggested rule contains parameters or masks, the suggestion comes pre-populated with parameter and mask values derived from the profiling. Once you accept the rule suggestion, it is automatically applied to the attribute.

For more information, see Rule Suggestions.

Rule suggestion example

DQ Rules Can Use Parameters

Previously, if you needed data quality rules that differed just in small details (for example, two rules with “Has 1 digit” and “Has 2 digits” conditions, respectively), you had to create multiple rules. With parameters, you can now create reusable rules, where you replace the constant values in rule logic with parameters, and then provide parameter values when applying the rule to the attribute.

For more information, see Create DQ Evaluation Rule.

Secret Management Service

The new secret management service feature allows you to connect and provide access to your central storage locations and retrieve secrets from them when connecting to a data source. This allows for more secure storage and management of application secrets and keys and removes the need to manually provide sensitive information when setting up connections.

Add new secret management service
Currently, the only supported provider is Azure Key Vault.
If you have previously configured Azure Key Vault credentials when connecting to a data source (either through driver properties in the case of relational databases or through the user interface in the case of Power BI and ADLS2 connections), see DQG 15.2.0 Upgrade Notes for information about how to align with the new secret management services.

Redesigned UI for Azure Key Vault Connection Credentials

On all connections, it is now possible to configure the use of Azure Key Vault through the user interface.

The new interface also allows for the retrieval of Azure Key Vault values from the secret management service configured in ONE.

Azure AD connection
When connecting to relational databases, it is no longer necessary to add driver properties in order to use Azure Key Vault.
If you have previously configured Azure Key Vault credentials when connecting to a data source (either through driver properties in the case of relational databases or through the user interface in Power BI and ADLS2 connections), see DQG 15.2.0 Upgrade Notes for information about how to align with the new secret management services.

Manage Access to Assets in Bulk

For more efficient user access management, you can now perform these actions in bulk:

  • Share access to assets.

  • Assign stewardship to assets.

For more information, see Share Access and Assign Stewardship in Bulk.

Support for OneLake

A dedicated connection interface has been added for OneLake: select OneLake when adding a new connection. OneLake is provided automatically with every Microsoft Fabric tenant and is designed to be the single location for your organization’s analytics data.

See OneLake.

OneLake connection settings

Support for Lakehouse SQL Analytics Endpoint

When you create a Lakehouse in Microsoft Fabric, it automatically generates an SQL analytics endpoint. Using this endpoint, you can work with delta lake files in the Lakehouse as if they were stored in an SQL database.

Lakehouse SQL analytics endpoint has been added to the list of possible connections when you are adding a new connection.

For more information about how to construct the correct JDBC string, see Lakehouse SQL Analytics Endpoint.

ONE Data

Deactivate or Limit ONE Data

The ONE Data module can now be turned off or limited in functionality using specific feature flags. There are three options:

  • ONE Data: Deactivate ONE Data entirely.

  • ONE Data Load: Turn off the option to load data from catalog items to ONE Data for data management and remediation.

  • ONE Data Load limited to reference data: Limit the option to load data to allow loading only reference data into the module.

How these settings are managed depends on your deployment type:

  • Self-managed deployments: The feature flags are included in the provided Ansible scripts.

  • Ataccama Cloud Dedicated deployments: These settings are managed by Ataccama. Contact Ataccama Professional Services for assistance.

  • Ataccama Cloud Essential/Professional/Enterprise deployments: These settings can be managed in the configuration interface (Cloud Portal), from the Settings tab > Experimental features section of a specific environment.

    ONE Data feature flags in Cloud Portal

By default, ONE Data is distributed as follows for all deployment types:

  • ONE Data is enabled.

  • Loading data from catalog items to ONE Data is enabled.

  • Loading only reference data to ONE Data is turned off.

Support for Aggregation and Component Rules

Data loaded to ONE Data from a catalog item that has component or aggregation rules applied now includes DQ results. Therefore, you can now select them when filtering records by DQ in ONE Data.

Data Stories

Enhanced Filter and Chart Settings

Filter and chart settings now have a more streamlined look and are optimized for usability on smaller screens. This includes reduced padding between components and smaller component versions, resulting in a tidier interface overall.

Visualization Builder Improvements

The Visualization Builder is now better adjusted for smaller screen resolutions, featuring a reduced default width for the attribute bar, an updated closing icon, and reduced padding (both vertical and horizontal). Likewise, switching between data table and visualization is more intuitive (using icons instead of text), and there is a shadow effect in the visualization area for better visual separation.

In addtion, you can now customize the formatting of numeric values in your visualizations. You can adjust decimal places, select separators for decimal places and thousands, add prefixes or suffixes, and abbreviate large numbers to better suit your preferences.

General UI Improvements

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

  • Revamped 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.

  • Editable slide names: Rename slides with a simple double-click, the same way you edit story or dashboard titles.

  • 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.


Improved Authentication

MDM Web App now utilizes Keycloak Session Idle Timeout and Session Max configuration effectively. You are now automatically logged out and notified via a popup dialog when the idle timeout or maximum session duration is reached.



Improved Authentication

RDM Web App now utilizes Keycloak Session Idle Timeout and Session Max configuration effectively. You are now automatically logged out and notified via a popup dialog when the idle timeout or maximum session duration is reached.
