Alerts notify operators of potential issues such as failed transformations, dropped data, growing backlogs, or resource constraints. Immediate notification allows teams to take corrective actions before problems escalate into downtime or data loss.

Automated alerts also reduce reliance on manual monitoring, enabling proactive operations at scale. Without alerts, performance or quality issues could go unnoticed until significant disruptions occur, impacting business processes and analytical outcomes.

Limitations of Alternative Approaches

Option A, which relies on print statements in code, is insufficient for large-scale streaming pipelines. Print statements provide unstructured, delayed feedback and cannot scale with high-throughput data flows. Option C, disabling metrics to reduce overhead, eliminates critical visibility, leaving teams blind to performance or data quality problems. Option D, reviewing dashboards weekly, is reactive and too slow for real-time pipelines, potentially resulting in missed opportunities to correct issues before they affect downstream analytics or user experiences.
