Data Observability Dashboards Improvements

This version brings the following usability improvements in Data Observability dashboards:

  • More control over which issues are closed when bulk-closing them in the issues table.

    To filter the issues that should be closed, select the date and issue type, or search for specific catalog items. Next, select Close issues (previously Close all issues).

    For more information, see Data Observability Dashboards, section Close issues.

  • Unified functionality on all tabs in the issues table:

    • On the All Issues tab, you can now search for catalog items, the same way as on other tabs.

    • On the Freshness tab, you can now sort issues by the Detected column, the same way as on other tabs.

Generate Full DQ Evaluation Rule Implementation Using AI

Available in Ataccama Cloud deployments only.

Generate full DQ evaluation rule implementation with Gen AI using natural language.

Go to the Implementation tab of one of your rules and select the Use AI to generate Rule logic and inputs option. Enter a plain text prompt using natural language in the Define the rule field.

Generate full rule implementations using AI

For more information, see Generative AI in ONE.

ONE Desktop

Remote Execution on Selected DPEs

Choose which engine will execute your plan remotely by specifying a DPE label in ONE Desktop.

This is particularly useful when you work with multiple DPE instances, such as hybrid DPEs and standard DPEs, enabling you to direct your plan execution to a specific engine. For example, define which engines can connect to private on-premise data sources or direct demanding or complex jobs to a DPE with more resources available.

To learn more, see Remote Plan Execution, section Remote execution on selected DPEs.

MDM

Native Amazon SQS Streaming Connector

We have introduced native support for Amazon SQS to replace the previous JMS-based implementation. To learn how to configure SQS streaming connector, see mdm-integration:amazon-sqs-connection.adoc.

Task Improvements

We have made several enhancements to simplify task management and improve usability:

  • Roles with edit permissions can now modify task names, descriptions, and severity levels.

    Task details editing

  • Assignee and Assignee group lists are sorted alphabetically for easier navigation.

  • Custom permissions now allow you to restrict task visibility only to entities that a role has permission to view. To learn more, see Configuring Permissions, section Configuring a custom permission scheme.

  • Task listings in MDM Web App display only one line of description, with full text accessible on hover and searchable using Ctrl+F.

    Task description example

New Matching Step Parallelism Configuration

We have improved matching step parallelism configuration. Newly introduced properties allow you to configure the number of threads at each level (partition, key, and rule) and set data thresholds to optimize parallel processing. To learn more, see Performance Tuning, section Matching step performance tuning.

History Plugin Persistence

We have introduced database persistence for history event handling. To learn more, see MDM Server Application Properties, section History plugin configuration.

Deprecation Notice

The following features will be deprecated starting from version 16. In case of any questions, contact Ataccama Support for assistance.

Event Publishers

All event publishers, except for the plan publisher, will be deprecated. If you use the deprecated publishers, migrate your existing logic to the plan publisher.

MS SQL and Oracle RDBMS

No further functionalities or optimizations will be developed for Microsoft SQL Server and Oracle RDBMS as MDM storage options. Current setups will remain functional, however, we recommend migrating to PostgreSQL. Alternatively, you can switch to Custom Ataccama Cloud, where we manage PostgreSQL on your behalf.

Draft to Task Migration

Automatic drafts to tasks migration will be removed. In case you are upgrading from version 13 or earlier to version 16, you need to first upgrade to version 15.4 LTS.

RDM

Export Records with Published Changes

You can now export records with published changes both through the RDM Web App and RDM REST API and use them for auditing purposes outside of RDM.

The export is available in the JSON format and contains information about the record primary keys, its identifier in the table, as well as the changed columns. This allows you to easily identify each record in a unique manner and see which values were modified, when, and by which user.

To export records from the web application, open the Change Log tab and narrow down your record selection using filters. Select View and then Export. The exported JSON file is then downloaded to your machine. For details, see RDM Change Log.

In addition, the Change Log tab now clearly shows whether any filters are currently applied or whether you are viewing the full changelog. This way, you can quickly make sure you are exporting the records you are interested in, as the filters used also determine which records are included in the export file. You can find this information above the record listing.

Export RDM Changelog

To export the changelog using the API, send a GET or POST request to the new /changelog endpoint. You can filter the records through query string parameters or the request body, respectively. To learn more, see RDM REST API, section Get records with published changes.

New Prometheus metrics

We have made it easier to keep track of the application state using the new ataccama_one_rdm_application_state metric. The metric reports the current status of the application and can be used together with the ataccama_one_business_ready metric to check whether the application can be used or not.

In addition, you can now find out how many HTTP requests the application received and how many users have edit permissions.

For more details, see RDM Monitoring Metrics.

Fixes

  • ONE-58423: Only published entities can now be referenced in the Referenced Object property type.

  • ONE-60201: Improved error messaging in Data Stories in cases where you don’t have access to a visualization. The application now clearly indicates whether the issue is due to insufficient permissions or because the visualization contains protected attributes that you cannot access.

  • ONE-60202: In Data Stories, visualization names are correctly displayed on dashboards even if data protection classification is applied to an attribute used in the visualization.

  • ONE-56934: In Data Stories, it was possible to create a new visualization in a collection without specifying a collection name. The Create a new visualization option is now not available until a collection name is provided, preventing you from creating unnamed collections.
