Exam AZ-204 topic 3 question 20 discussion

The given answer is correct.

Microsoft has obscrure names in documentation and has nothing to do with the azure component itself. "Delegate", "Host component", "Compute instance". How's remembering this from one page they wrote mean anything. We do not call any of them these when we implement the change feed processor

🛠 Think of it like this: Imagine you’re watching a door for packages 📦: Source container = The place where packages (data) arrive Lease container = A log of which packages you already saw Delegate = Your job (like moving the package somewhere or processing it) Host = The person doing the work

correct The change feed processor has four main components: The monitored container: The monitored container has the data from which the change feed is generated. Any inserts and updates to the monitored container are reflected in the change feed of the container. The lease container: The lease container acts as state storage and coordinates the processing of the change feed across multiple workers. The lease container can be stored in the same account as the monitored container or in a separate account. The compute instance(host): A compute instance hosts the change feed processor to listen for changes. Depending on the platform, it might be represented by a virtual machine (VM), a Kubernetes pod, an Azure App Service instance, or an actual physical machine. The compute instance has a unique identifier that's called the instance name throughout this article. The delegate: The delegate is the code that defines what you, the developer, want to do with each batch of changes that the change feed processor reads.

Question in my exam 22sept 2023

On my exam 2023sept

1. Monitored container > You want to track changes of the data you store 2. Lease container > A lease container is responsible for maintaining information about which workers are processing which data from the Monitored Container 3. Host > They represent the worker instances responsible for processing changes from the change feed 4. Delegates > Methods you define to handle actual changes detected by the change feed (so when the change feed receives changes, it invokes delegate methods) The difference between a monitored container and a host is that a host actually distributes work to delegates, while a monitored container tracks changes in data and gives that info to the change feed processor.

Answer is correct. *Note that the "Host" Component should be called Compute Instance instead. https://docs.microsoft.com/en-us/azure/cosmos-db/change-feed-processor
