public class ScalableTaskCount
extends BaseScalableAttribute

The scalable attribute representing task count.

         .cluster(cluster)
         .memoryLimitMiB(1024)

         .minCapacity(1)
         .maxCapacity(20)
         .build());
 scalableTarget.scaleOnCpuUtilization("CpuScaling", CpuUtilizationScalingProps.builder()
