Whats New In Our Products ?

Kelvin UI

What's New

  • Data Quality
    • New Dashboard for data quality analysis and general statistics
    • New Data Quality configuration page with pre-filling and visualisation and simulation
      • Pre-fills available: Asset Type, Connection, CSV.
    • New user and instance setting version migration system

What's Changed

  • Asset insights now uses Asset type as a regular view multi-select filter
  • Asset insights now comes with a Last Recommendation column out-of-the-box
  • Improved column spacing and last column numeric alignment that produces empty mid table spacing
  • More tables across the app now have the ability to resize columns
  • Improved recommendation modal (Data Explorer and Asset Insights table)
  • Improved actions modal (Data Explorer and Asset Insights table)
  • Improved app manager flows to account for Data Quality
  • Improved keyboard accessibility in application modals
  • Improved instance setting control over Asset Control Panel
  • Improved filters on Administration dashboard
  • Bug fix where cluster duplicates validation didn’t allow for cluster creating
  • Overall performance improvements around App Manager, Connections and Guardrails
  • Overall improvements and bug fixing.

Kelvin API

What's New

Edge API & Workload Management
  • Introduced new internal endpoints for cluster synchronization between the server and edge.
  • Implemented encryption and decryption for secrets transmitted between the server and edge to enhance security.
  • Added support for workload imports using kelvin-provision and bulk delete of workloads.
  • Added protection for workload actions, limiting updates only to staged workloads.
  • Extended workload response fields with improved synchronization and detailed timing logs.
  • Added more informative API error responses and improved workload status handling.
  • Implemented automatic gateway deployment for Kelvin Apps regardless of spec version, injecting missing environment variables.
  • Added dynamic edge-sync image updates across all cluster types.
  • Implemented final manifest rebuild on edge workload changes.
Data Quality Features
  • Introduced a complete Data Quality Framework, including:
    • Data Quality Cloud Worker for distributed computation.
    • Scheduler workflow for time series data quality scoring.
    • Bulk upsert endpoint for data quality entries.
    • Validation for disabled data quality algorithms.
    • Automatic deletion of data qualities when assets or datastreams are removed.
    • Workers to calculate data quality scores for assets and datastreams.
    • Statistics and metrics endpoints for reporting.
    • Performance improvements across all data quality workers.
    • Added filtering by asset and datastream name in data quality endpoints.
ClickHouse Importer
  • Added ClickHouse importer for app-related data.
  • Introduced indexes and improved query performance.
  • Added internal configuration to reset data by dropping all ClickHouse tables.
  • Expanded to import apps, assets, and workloads.
CQRS Improvements
  • Added event skipper for NATS publisher to improve event throughput.
  • Enhanced snapshot logic, fixing uncommitted event handling and connection errors.
  • Introduced context cancellation support for replay operations.
General Platform Updates
  • Added utility for Gateway feature compatibility validation.
  • Added asset information injection (title, type, and type title) into workload runtime.
  • Added filters for asset insights to return only assets with data quality.

What's Deleted

  • Edge Sync was extracted from the main AF repository and moved to its own repository for independent deployment (refactor(edge-sync)).
  • Legacy dataflow-go dependency removed and migrated to core-common-go on GitHub.

What's Deprecated

  • app.yaml-based workload definitions are deprecated.
  • Replaced by Workloads manifest and runtime management system in edge-k8s (feat(edge)).
  • Manual gateway version handling is deprecated in favor of automated gateway deployment.

What's Changed

Edge & API Refactor
  • Edge API refactored for improved synchronization and manifest control.
  • Edge-K8s refactored to use the workload manifests and runtime.
  • Improved sync behavior to handle skipped or partial syncs gracefully.
Security Enhancements
  • Introduced encryption of secrets across edge-server communication channels.
Data Quality Enhancements
  • Normalized data quality scores (0–100).
  • Enforced date-time formats in ClickHouse statistics queries.
  • Improved data quality score weighting and configurability.
API and Performance
  • Enhanced ClickHouse timeseries read loop for performance and memory efficiency.
  • Fixed fast-path serialization and value fill issues in the timeseries API.
  • Improved API transaction isolation and asset event listener logic.
Infrastructure and Dependencies
  • Bumped kube-state-metrics to version 2.17.0.
  • Refactored multiple dependencies to use GitHub repositories.
  • Improved ClickHouse importer performance and index optimization.
Bug Fixes
  • Fixed manifest encoding issues with escaping backslashes.
  • Fixed data quality statistic endpoint responses.
  • Fixed potential deadlocks and concurrency issues in edge-k8s.

Summary

  • The refactor focuses on security, modularization, and data integrity across Kelvin’s edge and data quality ecosystems.

Key Highlights:

  • Secure secret handling between server and edge.
  • Full integration of workloads manifests and runtime systems.
  • Data quality framework enhancements.
  • ClickHouse performance improvements.
  • Simplified synchronization for workloads and apps.
