A is just a static number, not a good fit at all.

Wait, can KTables really handle that much data?

The items returned might not be the best choice either, since they don't represent a current state like the inventory does.

I practiced a similar question, and I feel like the transaction stream is more of a KStream, not a KTable.

I'm not entirely sure, but I remember something about KTables being used for aggregating data. Maybe the money made until now could work?

I think a KTable would be best for something that represents a current state, like the inventory contents right now.

The transaction stream is the clear winner in my opinion. It's a continuously updating dataset that represents the core business activity, so modeling it as a KTable makes the most sense.

The transaction stream is definitely the way to go here. KTables are perfect for modeling datasets that are constantly being updated, like the stream of shoe purchases at the store.

Hmm, I'm a bit unsure about this one. Is the inventory contents right now also a good option since it's a continuously changing dataset? I'll have to think this through carefully.

This seems like a straightforward question. The transaction stream would be a great candidate to model as a KTable since it represents a continuously updating dataset of shoe purchases.

I'm a little confused about the differences between the options. Is the "money made until now" a good choice, or is that better suited for a different data structure? I'll need to review the Kafka Streams concepts again.

Haha, money made until now? What is this, a lemonade stand? We're running a serious shoe store here, people. Gotta go with the transaction stream.

Items returned? Really? That's just a small part of the business. I'd focus on the big picture and go with the transaction stream.

The transaction stream seems like the obvious choice here. That's the core of our business - we need to keep track of all the shoes that are being bought and sold.
