KEDA

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.

        description: The URL path component configured in the KEDA ScaledObject trigger metadata url field. Identifies which
          metric endpoint to query.
    docs: Returns a JSON (or other format) payload containing a numeric metric value that KEDA extracts using the configured
      valueLocation path (GJSON notation). The response can include nested objects; KEDA will navigate to the configured path
      to read the scalar value. The extracted value can be an unquoted integer (e.g., 42) or a Kubernetes quantity string
      (e.g., "10Mi"). An optional targetValue or activationValue can be compared against this number to determine scaling
      behavior.
