5 Data Pipeline Anti-Patterns That Silently Wreck Your Stack (And How I Fixed Them)

Most pipelines don’t fail overnight—they decay through shortcuts. This guide breaks down five destructive anti-patterns: monolithic DAGs, no schema contracts, non-idempotent writes, poor observability, and hardcoded configs. Each section includes real-world fixes—from partition overwrites to schema validation and metrics-driven monitoring—so you can design pipelines that fail safely, recover fast, and stop triggering 3AM alerts.
