PICKUP DATA: A Kafka Adventure Game
summary
Built a text‑based adventure inside Apache Kafka using Kafka Streams, two logs (commands and responses), stream splits, aggregations into tables, joins with a global table for standing data, and stateful reductions for location and inventory. The demo supports pick up, use, movement and inventory, emits responses back to users, and runs live. It demonstrates practical Kafka Streams tricks, shows event‑sourcing style rollups for position and knapsack state, and proves the idea actually works.
