What's new in Cloudera Data Visualization 7.2.8

Cloudera Data Visualization 7.2.8 was released on October 30, 2024 introducing the following changes.

New features and improvements

VIZ-825

You can analyze and summarize data characteristics in a dataset with the new Data Profiling feature. This tool helps you to understand data quality, structure, and identify patterns and trends for more informed decision making. For more information, see Working with data profiling.

VIZ-2585, VIZ-2842

UI and performance improvements for Activity Log and Historical Log tables.

VIZ-2782, VIZ-2915

Clone and Delete actions are now available from the Dataset Detail page for users with appropriate permissions.

VIZ-2801

Discontinued support for older versions of several external database metastores to ensure compatibility with the latest security, performance, and feature updates introduced in Django 4.2.

Affected database versions:

PostgreSQL 11 and lower
MariaDB 10.3 and lower
MySQL 5.7 and lower
Oracle Database Server versions lower than 19c
SQLite versions lower than 3.21.0

Users running any of the above database versions will need to upgrade their external database metastores to maintain full functionality with Cloudera Data Visualization.

Supported database versions:

PostgreSQL 12+
MariaDB 10.4+
MySQL 8+
Oracle Database Server 19c+
SQLite 3.21.0+

To ensure compatibility and full feature support, upgrade to one of the supported database versions. Failure to upgrade to a supported version may lead to database connection issues, data integrity risks, or unexpected behavior in Cloudera Data Visualization features.

VIZ-2804

Added an option to create a new schedule interval in the Edit Job modal.

VIZ-2808, VIZ-2941

Introduced two new visual settings for histogram visuals. You can now set minimum and maximum values under Settings > Basic, and separate columns using the checkbox available under Settings > Marks.

Fixed issues

VIZ-987: Fixed an issue where generation of new thumbnails while importing visual artifacts failed with an error message.
VIZ-2324: Removed the Explore visuals icon from the Dashboard Builder when the setting is disabled.
VIZ-2720, VIZ-2784, VIZ-2916: Additional performance and security improvements.
VIZ-2819, VIZ-2897, VIZ-2898, VIZ-2899, VIZ-2900, VIZ-2901, VIZ-2903, VIZ-2904, VIZ-2905: Fixed critical and high-severity package vulnerability issues identified in Cloudera Data Visualization 7.2.7.
VIZ-2869, VIZ-2923: Fixed an issue where dashboards with large numbers of visuals and filters would freeze when switching sheets.
VIZ-2870: Filters with app-level filter visibility now work as expected when cloning and importing visual artifacts.
VIZ-2871: Partitioned data extract refresh now works as expected with Impala tables running in Cloudera Private Cloud Base 7.1.9.
VIZ-2880, VIZ-2945: Fixed an issue where CSV/Excel content downloads occasionally saved the HTML version of the page content instead of the requested data.
VIZ-2889: You can no longer reuse an existing data connection name when creating a new connection. When cloning a data connection, the system will automatically append a version number (for example: "_1") to the name of the new connection. This update resolves an issue where duplicate data connection names previously caused conflicts during visual artifact imports.
VIZ-2919: Searching within a filter now properly limits results based on columns specified as filter fields in the Filter Settings.
VIZ-2925, VIZ-2962: Visual artifact import and export for artifacts containing segments now work as expected.
