AI-200 Event Driven Integration Practice Question
You are optimizing an Azure Event Hubs stream processing application in Python. Messages are being processed too slowly, and you notice high CPU utilization on the consumer instance due to synchronous network I/O. Which programming model should you adopt to maximize ingestion throughput?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use the asynchronous Event Hub client library (`azure-eventhub.aio`) with `asyncio` for non-blocking I/O operations.
For high-performance asynchronous I/O in Python with Azure Event Hubs, developers should use the `azure-eventhub` asynchronous client library (`aiohttp` / `asyncio`) to process events concurrently.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Increase the partition count of the Event Hub to 1,000 partitions.
Why it's wrong here
Excessive partitions without adequate consumer threads increases overhead and exacerbates context switching.
- ✗
Switch from Event Hubs to Azure Storage Queues for parallel processing.
Why it's wrong here
Storage Queues are designed for low-throughput work queues, not high-speed telemetry streaming.
- ✗
Migrate all consumer code to use synchronous REST API polling over HTTPS GET requests.
Why it's wrong here
REST polling is extremely inefficient and slow compared to persistent AMQP connections.
- ✓
Use the asynchronous Event Hub client library (`azure-eventhub.aio`) with `asyncio` for non-blocking I/O operations.
Why this is correct
Async/await patterns in Python prevent thread blocking during network calls to Event Hubs, dramatically increasing throughput.
