Summary: Azure Monitor metric showing % of provisioned throughput used; flags hot partitions.
Overview
Normalized RU Consumption is an Azure Monitor metric that reports the percentage of provisioned throughput being utilized by a container or partition over a given period, helping identify hot partitions (nearing 100%) or under-provisioned/over-provisioned throughput, without needing to manually calculate raw RU usage against the provisioned amount.

DP-420 Style Practice Questions
Q1. What does the Normalized RU Consumption metric represent?
- A. The percentage of provisioned throughput being consumed by a container or partition
- B. The total number of documents stored
- C. The number of regions data is replicated to
- D. The number of indexed properties
Q2. A partition consistently showing Normalized RU Consumption near 100% likely indicates what?
- A. A hot partition that may be throttling requests and could benefit from better partition key distribution
- B. The partition key is optimally distributed
- C. TTL needs to be enabled
- D. The consistency level should be lowered
Answer Key
Answers are listed at the very end so you can attempt the questions first.
- Q1 (Normalized RU Consumption): A. The percentage of provisioned throughput being consumed by a container or partition — Normalized RU Consumption shows RU usage as a percentage of the provisioned throughput, making hot partitions easy to spot.
- Q2 (Normalized RU Consumption): A. A hot partition that may be throttling requests and could benefit from better partition key distribution — Consistently high normalized RU consumption on a partition signals a hot partition at risk of throttling (429s).
