Real-time data pipelines are not just about speed. Even when events are processed in milliseconds, late arrivals, duplicate records, stale data, and recovery failures can lead to incorrect business decisions. This article explores the hidden costs of streaming architectures and explains why data freshness, correctness, fault tolerance, and operational efficiency matter as much as low latency. It also introduces a practical framework for designing reliable, production-ready streaming systems using technologies like Apache Kafka and CDC.
