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

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?

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.

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.
