Release 5.15

April 2025

Whats New In Our Products ?

Kelvin UI

  • New select all feature all tables allows the user to select all resources across pages;
  • New Manual Controls page on the recently revamped Asset Page, allows for better visualization, grouping and inline control changes.
  • New Application Management features:
    • Workload detail page now allows for directly adding assets;
    • Bulk workload updates;
    • Improved Deploy workload flow;
  • Overall improvements and bugfixes;

Kelvin API

  • New Endpoints:
    • Add Workload Resources (/apps/workloads/{workload_name}/resources/add)
      • Allow users to add resources to an existing workload
    • Remove Workload Resources (/apps/workloads/{workload_name}/resources/remove)
      • Allow users to remove resources from a workload
    • Update Workloads Bulk (/apps/workloads/bulk/update)
      • Update a list of workloads bulk
      • All workloads being updated must be running to the same Application
      • All configurations sent will be applied to all workloads
      • All resources running in the workloads must be sent in the request. The API will distribute them to the corresponding workloads they’re in
  • Some Internal Improvements
    • Deployment of Applications/Workloads now has a new validation being performed in the API
      • Only one workload in the platform can be producing output data for a Resource/Datastream
      • When a workload is deployed, we identify the Resource/Datastream pairs that will be owned/produced by it
        • What determines if a resource/datastream is owned by a workload is the value of way
        • If way is output, input-cc or input-cc+output, it means it’s owned by the workload
      • If, when deploying a workload, a resource/datastream is sent as an owned resource and this resource is already owned by another workload, the API will through an error saying the resource context is already locked!
    • The Deployment of Applications/Workloads will now use App defaults to fill some fields in the workload if these fields were not sent in the request
      • The fields being automatically filled, if not sent, are the following:
        • runtime.resources[*].datastreams , filled with information from App Version io and, if set, with defaults.app.io_datastream_mapping
        • runtime.configuration , filled with information from App Version defaults.app.configuration
        • system , filled with information from App Version defaults.system
        • deployment.deployment_type , filled with information from App Version defaults.deployment.deployment_type
        • deployment.max_resources , filled with information from App Version defaults.deployment.max_resources
        • deployment.target , filled with information from App Version defaults.deployment.target
