PICKUP DATA - A Kafka Adventure Game

on YouTube ↗43m

" summary

Builds a playable text adventure implemented end to end on Apache Kafka using websockets, KSQL and Java streams, with commands written to a command stream and responses read from a response stream. Implements map as a global table, per-user position as a sharded table, joins to enrich location, a rules table for item use, and a fold-based inventory knapsack that works in real time so the demo actually runs. Claims easy horizontal scaling and low latency and cites two million events a second and stateful tables as streams.
