Description

The CFN specification for enum PredefinedMetric includes 5 members which are absent from CDK:

• AppStreamAverageCapacityUtilization
• CassandraReadCapacityUtilization
• CassandraWriteCapacityUtilization
• ComprehendInferenceUtilization
• NeptuneReaderAverageCPUUtilization

I needed the one for AppStream and expected feature parity with CFN but didn't find it.

Use Case

Implement autoscaling using predefined metrics

Proposed Solution

Add the enum members that are present in CFN but not CFK
