What's new in Cloudera Data Visualization 8.0.4

Cloudera Data Visualization 8.0.4 was released on May 30, 2025, introducing the following changes.

New features and improvements

This release includes a range of enhancements across data analysis, system configuration, user experience, and platform support.

User experience and interface enhancements

VIZ-1708 – Threshold email improvement: Added a Test Trigger button in the Email modal, allowing you to validate trigger conditions before saving or scheduling, improving setup accuracy. For more details on setting up a threshold email, see Creating new email jobs.
VIZ-2476, VIZ-3294 – Redesigned Current Load view for improved clarity: Updated the Current Load tab under Show Usage Info for improved clarity.
VIZ-3330, VIZ-3332 – Improved AI Visual formatting: Enabled additional formatting settings for the AI Visual. The welcome message now supports Markdown styling for better presentation when Markdown is enabled in the Chat Appearance setting. Additionally, arc-ai-XX classes were added to the AI-visual to support custom CSS styling.

Data profiling and analytics improvements

VIZ-2979 – Correlation: Added the ability to select specific fields for correlation analysis and introduced a separate correlation tab in data profiling. Supports calculation using Pearson correlation coefficient.
VIZ-3194 – New data profiling cards for Date and Boolean fields: Introduced dedicated profile cards for date and boolean columns in datasets, improving data profiling clarity data connections.

Query and data handling enhancements

VIZ-3007 – Trino data connection [Technical Preview] enhancements: Added full support for Trino SQL syntax highlighting and autocomplete, including many built-in functions across categories like aggregate, conditional, date/time, string, JSON, arrays, and more.
VIZ-3269 – Improved database name handling during data addition: Modified validation rules for database names when adding data. Previously, names starting with non-alphabetic characters were rejected, which caused issues for valid real-world database names. The updated logic skips unnecessary validation, allowing users to add data to existing databases regardless of naming conventions.

AI and chatbot enhancements

VIZ-3328 – Improved AI chatbot context query for Solr (Technical Preview) connections: Enhanced the accuracy of AI chatbot context aggregation in Solr by consolidating similarity search and aggregation into a single request, reducing lexical errors and improving result precision.
VIZ-3384 – Improved AI error handling and custom streaming transformers: The response transformer logic now runs earlier in the process, providing more meaningful AI Visual errors.

Fixed issues

VIZ-2257: Resolved an issue where queries run by other users were incorrectly shown as belonging to the logged-in user in the Webserver Stats active queries summary.
VIZ-3203, VIZ-3362, VIZ-3363: Fixed critical and high-severity package vulnerability issues identified in Cloudera Data Visualization 8.0.3.
VIZ-3318: Fixed an issue preventing users from creating annotations on newly saved dashboards until the page was refreshed.
VIZ-3339: Resolved an issue where SQL filter validation incorrectly flagged expressions containing the keyword “from” inside string literals with escaped single quotes. The validation logic was improved to properly recognize and handle escaped quotes within string literals, preventing false errors during filter expression validation.
VIZ-3345: Resolved an issue where importing a cloned dashboard multiple times on the same data connection caused errors due to mismatched parent_report_id handling. The import process now properly manages parent_report_id to prevent repeated replacement attempts of identical dashboards.
VIZ-3347: Resolved an issue where importing the same dataset multiple times caused the server to repeatedly replace it because of mismatched version_name values generated during import.
VIZ-3349: Fixed an issue where canceling a query would permanently terminate the associated connection thread, leading to thread pool exhaustion. The fix introduces proper handling of canceled queries by adding the missing CANCELED attribute to the Runner class.
VIZ-3359: Addressed a performance issue where deleting dashboards took significantly longer after upgrading to Cloudera Data Visualization 8.0.2. Optimized query handling to reduce the number of database calls during dashboard deletion.
