• Metadata Records Fetch Limit for SQL Queries: Users can now configure the number of records fetched from metadata during SQL queries by setting the value of the kyvos.query.metadataread.maxlimit property.

Writeback on Semantic Models

This release introduces writeback capability for semantic models, allowing users to update cell values for specific dimension combinations directly within the model. Business users can now modify data from Microsoft Excel and Kyvos Viz. While analyzing semantic model data, removing the need for external data updates and enabling more interactive, scenario-driven analysis.

Temporary Data Purge Configuration from Kyvos DFS

This release supports automatic cleanup of temporary data generated during semantic model processing failures. Users can control this by configuring the TEMP_DATA_RETENTION_DURATION property in the ‘biserver.properties’ file, ensuring optimized storage usage and easier maintenance.

Upgraded Apache Tomcat Version

Kyvos and Kyvos Manager have been upgraded to Apache Tomcat 10.1.49.

Cloud Support Enhancements

This release comes with the following enhancements for AWS, Azure, and GCP clouds.

Azure Enhancements

• PostgreSQL 16 Support for Automated Deployments: This release supports PostgreSQL 16 (installed as a service) on the Kyvos Manager node as the repository for Kyvos Manager and Kyvos. In automated deployments, PostgreSQL is installed automatically, whereas in wizard deployments, users must first install PostgreSQL 16 before deploying Kyvos. This ensures compatibility with supported operating systems, improving performance and reliability.
  For further details, see No-Spark and Spark documentation.

GCP Enhancements

• Consistent Cross-Region Disaster Recovery: This release introduces cross-region disaster recovery for clusters, offering a consistent approach. Users can create resources using Terraform scripts in the GCP enterprise cloud to deploy disaster recovery clusters automatically.

Semantic Model Enhancements

• Optimization in Semantic Model Processing Through Streamlined Query Logging: Kyvos now captures only essential query execution details, reducing storage consumption and logging overhead while preserving all information required for debugging and analysis. This optimization improves semantic model processing performance, removes redundant fields, and maintains full support for debugging, auditing, query replay, and recommendation framework functionality.

Kyvos Viz. Enhancements

This release comes with the following Kyvos Visualization enhancements:

• Email Multiple Filter Combinations in a Single PDF or Image: Kyvos now supports emailing multiple dashboards with different filter combinations as a PDF or image. This feature supports dynamic filtering, simplifies distribution, and enables comparative analysis in a single export.

• Chart Rendering Animation Support: Users can enable animations during chart rendering for smoother visuals. Animation is disabled by default and can be enabled by setting the enableAnimation property to ‘true' in the 'portal.properties’ file. This feature supports animations for Area, Bar, Column, Curve, DotPlot, Funnel, Gantt, Line, PackedBubble, Pie, Scatter, TreeMap, and Waterfall charts.

New Properties

This release comes with the following new property:

• kyvos.query.metadataread.maxlimit: Limits the record to be fetched from metadata for SQL queries.

• TEMP_DATA_RETENTION_DURATION: Specifies the maximum duration (in hours) for which the system retains temporary or intermediate data generated during semantic model processing.
