Problem

A payments company runs every card transaction through a fraud check that has to flag bad charges within seconds, while a vendor order API gets pulled once an hour to feed the finance team's reporting. Design both ingestion paths on one platform, each sized to the freshness its consumer actually needs.

Summary

Fraud counts in seconds, finance counts by the hour. Build one platform that serves both.
