DYANMODB_WRITE_CAPACITY_UTILIZATION

(deprecated) DYANMODB_WRITE_CAPACITY_UTILIZATION.

Deprecated:: use PredefinedMetric.DYNAMODB_WRITE_CAPACITY_UTILIZATION
See:: https://docs.aws.amazon.com/autoscaling/application/APIReference/API_PredefinedMetricSpecification.html
Stability:: deprecated

DYNAMODB_READ_CAPACITY_UTILIZATION: Percentage of provisioned read capacity units consumed by a DynamoDB table.

DYNAMODB_WRITE_CAPACITY_UTILIZATION

Suffix dummy is necessary due to jsii bug (https://github.com/aws/jsii/issues/2782). Duplicate values will be dropped, so this suffix is added as a workaround. The value will be replaced when this enum is used.
