 The Normalized RU Consumption metric is a metric between 0% to 100% that is used to help measure the utilization of provisioned throughput on a database or container. The metric can also be used to view the utilization of individual partition key ranges on a database or container. One of the main factors of a scalable application is having a good cardinality of partition keys.
 The chart below shows if your application’s high RU consumption is because of hot partition.
