Kelvin UI¶

New Features¶

Asset Control Panel Views – Users can now create and switch between multiple widget views, enabling customized workflows per use case.
Inline Recommendations in Asset Insights – Recommendations are now displayed directly within the Asset Insights table for faster contextual actions.
Inline Data Explorer in Asset Insights – Data Explorer visualizations can now be accessed directly from Asset Insights without leaving the page.
Data Export for All Tables – All tables across the platform now support data export in standard formats.

Enhancements¶

Asset Control Panel Widget Management – Added widget remove button, improved visual feedback, and introduced clear saving-state indicators for a smoother editing experience.
Data Quality – Data Quality metrics are now user-manageable, with custom metric support, updated stale-detection logic, and grouping by Data Stream and Asset.
Data Explorer – Added Y-axis auto-scale toggle, introduced Light Mode, removed redundant polling indicators, and improved data-fetching performance.
JSON Schema Forms – Major overhaul of the JSON Schema form engine and validation system, improving consistency and reliability across all editable forms and tables.
Asset Insights Table – Improved navigation persistence and caching, maintaining table context (page, filters, and search) when returning to the view.

Bug Fixes¶

General bug fixes and stability improvements across the platform.

- Data Quality:
  - Refactored the interval strategy alignment between Influx & ClickHouse.
  - Return empty statistics when the asset type has no assets.
  - Use the asset datastream count instead of the timeseries data for aggregation.
  - Asset aggregation now accounts for data quality configurations.
- API timeseries:
  - Improvements in the migrator to avoid memory “blow-up”.
  - Added definer permissions for ClickHouse views.
  - Minor performance improvements and bug fixes.
  - Added views for the last values and a back-filler job.
- API Orchestration:
  - Fixed HA join script information.
Developer Experience / Internal Improvements:
- Numerous refactors to Data Quality, Data Tag, API App, and ClickHouse Importer codebases.
- Refactor edge-k8s and workload deployments to support app.bin + manifests.bin.
- Improved performance:
  - Asset Insights API (apps portion).
  - Properties API.
- Test improvements:
