  KEDA (Kubernetes Event Driven Autoscaling) is a CNCF graduated application
  autoscaler that drives scaling of any container in Kubernetes based on the
  number of events needing to be processed. It extends Kubernetes with custom
  resources for defining scaling behavior and supports over 50 built-in scalers
  for event sources including Kafka, RabbitMQ, AWS SQS, Azure Service Bus,
  and Prometheus.

    name: KEDA Metrics API
    description: >-
      External metrics API server that exposes event-driven metrics from
      configured scalers to the Kubernetes Horizontal Pod Autoscaler. It
      implements the Kubernetes external metrics API interface, allowing
      the HPA controller to query scaler-derived metrics when making
      scaling decisions.

    description: >-
      The ScaledObject custom resource defines the mapping between an event
      source and a Kubernetes Deployment, StatefulSet, or custom resource
      that should be scaled based on event metrics. It specifies trigger
      scalers, scaling thresholds, min/max replica counts, and cooldown
      periods for workload-based autoscaling.

    description: >-
      The ScaledJob custom resource defines the mapping between an event
      source and Kubernetes Jobs that should be created in response to
      events. Unlike ScaledObject, ScaledJob creates new Job instances
      to process each unit of work rather than scaling existing
      long-running deployments, making it suited for batch workloads.

    description: >-
      The TriggerAuthentication and ClusterTriggerAuthentication custom
      resources define authentication parameters for KEDA trigger scalers,
      allowing credentials to be sourced from Kubernetes Secrets, environment
      variables, pod identity providers such as AWS IRSA or Azure Workload
      Identity, or HashiCorp Vault without embedding them in the ScaledObject.

    name: KEDA CloudEventSource API
    description: >-
      The CloudEventSource and ClusterCloudEventSource custom resources define
      HTTP or Azure Event Grid destinations where KEDA delivers CloudEvents
      when scaling events occur. Events follow the CloudEvents specification
      v1.0 and carry reason codes and messages for events such as ScalerError,
      ScaledObjectReady, ScaledObjectDeleted, and AuthenticationFailed.
      Optional event type filters allow consumers to subscribe to only the
      events they care about.
