" summary

Shows how to wire a toy trade matching engine using Apache Pulsar and Quarkus with DataStax Astra Streaming as the managed Pulsar cloud, creating a tenant and topics in seconds and demonstrating producer/consumer code and Pulsar Functions for on‑the‑fly transforms. Design uses two streams for buyer/seller topics, subscribers compare price and timestamp to emit matches. Demonstration stops short of a full production engine but proves end‑to‑end wiring and cites $0.13 per million messages as an example cost.
