[All Salesforce Certified Heroku Architect (Plat-Arch-206) Questions]

Universal Containers (UC)uses Apache Kafka on Heroku to stream shipment inventory data in real time throughout the world. A Kafka topic is used to send messages with updates on the shipping container GPS coordinates as they are in transit. UC is using a Heroku Kafka basic-0 plan.The topic was provisioned with 8 partitions, 1 week of retention, and no compaction. The keys for the events are being assigned by Heroku Kafka, which means that they will be randomly distributed between the partitions.

UC has a single-dyno consumer application that persists the data to their Enterprise Data Warehouse (EDW). Recently, they've been noticing data loss in the EDW.

What should an Architect with Kafka experience recommend?

AEnable compaction on the topic to drop older messages, which will drop older messages with the same key.

BUpgrade to a larger Apache Kafka for Heroku plan, which has greater data capacity.

CUse Heroku Redis to store message receipt information to account for 'at-least' once delivery, which will guarantee that messagesare never processed more than once. Scale up the consumer dynos to match the number of partitions so that there is one process for each partition.

Using Redis for message receipts is a smart move for reliability!

Wait, why are they losing data if they're using Kafka? That seems odd.

Upgrading the plan could definitely solve capacity issues.

Compaction won't help with data loss, just older messages.

Sounds like they need to scale up those consumer dynos!

Scaling up the consumer dynos makes sense, but I’m a bit confused about how that interacts with the partitions. Would we really need one consumer per partition?

Using Redis for message receipt sounds familiar, especially for ensuring 'at-least' once delivery. I think we practiced a similar scenario in class.

I think upgrading the Kafka plan could be a good option, but I wonder if that alone would solve the data loss issue.

I remember we discussed the importance of message delivery guarantees in Kafka, but I'm not sure if enabling compaction would really help with data loss.

Whoa, this is a tricky one. I don't want to mess up the termination process and end up in legal trouble. Maybe I should review the company's employee handbook before answering this.

Hmm, I'm a bit unsure about the differences between shared file systems and cloud storage for high availability. I'll need to think this through carefully.

I like how C tackles the problem from multiple angles - the Redis store and the scaled-up consumers. That's a more robust solution.

Compaction might help with older messages, but it won't address the data loss issue. C is the best option to guarantee message delivery.

Option B seems like overkill. Upgrading the Kafka plan is not necessary if the issue is with the consumer application.

I think the correct answer is C. Using Heroku Redis to store message receipt information and scaling up the consumer dynos will help ensure at-least once delivery and prevent data loss.
