I'll take 'Things I Don't Want to See in My Kafka Cluster' for 500, Alex. A purchase stream? What is this, Black Friday at Walmart?

Option C is the only one that makes sense to me. I mean, who wants to be on the receiving end of a 'purchase stream'? Sounds like a recipe for a data firehose.

I was totally going to choose option A, but then I realized that's just way too many streams. Maybe if we had a really complex use case, but for a simple ecommerce site, that seems overkill.

I agree, having separate streams for each entity might be too much for a simple ecommerce site.

I see your point, Lemuel. Having Purchase as stream and Product as table could provide more flexibility and scalability in the long run.

I disagree, I believe B) Purchase as stream, Product as table, Customer as table makes more sense for this scenario.

Option D seems interesting, but I'm not sure why we'd want the customer to be a stream. Wouldn't that make it harder to look up customer information?

I think A) Purchase as stream, Product as stream, Customer as stream is the natural way to model this data.

I think option B is the most natural way to model this data. Purchases are events, but products and customers are more like tables that we need to look up.

That's true, it provides a good balance between real-time processing and the ability to look up historical data.

But having purchases as a stream allows for real-time processing and analysis of the data.
