UpdateEndpointWeightsAndCapacities

Source: src/AWS/SageMaker/UpdateEndpointWeightsAndCapacities.ts

Runtime binding for sagemaker:UpdateEndpointWeightsAndCapacities — shift traffic between an endpoint’s production variants (or resize one variant) without redeploying.

Bind this operation to an Endpoint inside a function runtime to get a callable that automatically injects the endpoint name. Only applies to instance-based variants (serverless variants have no weights/capacities); the endpoint transitions through Updating back to InService.

Shifting Traffic

// init
const updateWeights =
  yield* AWS.SageMaker.UpdateEndpointWeightsAndCapacities(endpoint);

// runtime
yield* updateWeights({
  DesiredWeightsAndCapacities: [
    { VariantName: "Blue", DesiredWeight: 9 },
    { VariantName: "Green", DesiredWeight: 1 },
  ],
});
