AddInstanceFleet

Source: src/AWS/EMR/AddInstanceFleet.ts

Runtime binding for elasticmapreduce:AddInstanceFleet — adds a task instance fleet to the bound cluster (instance-fleet clusters only; TASK fleets can be added after launch).

Scaling the Cluster

const addFleet = yield* AWS.EMR.AddInstanceFleet(cluster);

const { InstanceFleetId } = yield* addFleet({
  InstanceFleet: {
    InstanceFleetType: "TASK",
    TargetSpotCapacity: 2,
    InstanceTypeConfigs: [{ InstanceType: "m5.xlarge" }],
  },
});
