You are creating a Kafka Streams application to process retail data.

Table→ Product, Customers

Stream→ Orders_Placed, Shipment_Of_Orders

Tablesrepresent slowly changing,reference data— e.g., customer profiles, product info.

Streamsrepresentreal-time event data— e.g., orders placed, shipments processed.

FromKafka Streams Documentation:

“Use KTable for reference datasets, and KStream for event-based processing such as orders or logs.”
