NEW QUESTION # 164
You have an Azure Cosmos DB for NoSQL account that hosts a container named Container1.
You implement a change feed processor.
You discover that the processor is processing changes more slowly than the changes occur in Container1.
You need to resolve the issue.
What should you use?
Answer: D
Explanation:
To handle change feed lag in Azure Cosmos DB, you can use the Change Feed Estimator to monitor the number of pending changes. This metric acts as a signal to scale your Change Feed Processor instances horizontally.
How the Estimator Works
The Estimator is a "sidecar" logic that measures the difference between the last processed item (stored in the lease container) and the latest change in the monitored container.
Frequency: It typically polls every 5 seconds (customizable).
Resource Usage: Each estimation consumes Request Units (RUs) from both the monitored and lease containers.
Independence: It can be deployed as a standalone instance separate from your processors to avoid impacting their performance.
