Claims a working Hazelcast Open Source pipeline that processes Kafka events in-memory with SQL enrichment and sliding windows to hit millisecond SLAs, not batch latency. Demo runs locally from a jar, reads one Kafka topic once, fans data to multiple Python/Java models, joins streaming and historical maps for enrichment, and outputs decisions; deployment options are host, edge, farm. Targets are sub-100ms (some banks 20ms) and five nines reliability while reducing false positives >$100M per year.
