Design a system correlating CI/CD deployments with observability metrics
Tests event-driven correlation and temporal join patterns across distributed data. Strong answers outline: async deploy event ingestion, time-windowed metric joins with version tags, and handling clock skew.
Tests whether you can bridge event-driven CI/CD pipelines with time-series observability using temporal joins and idempotent tagging. A strong design includes: async deploy event ingestion via webhooks or message queues; a correlation service that overlays deployment markers on metric windows; version tagging injected into telemetry; and clock skew handling. Red flag: proposing simple batch polling instead of event-driven correlation, or ignoring the hard problem of aligning timestamps across distributed systems.
