What this is

What counts as Circuit-breaker support?

A circuit breaker is the pattern of stopping a pipeline when an input fails validation, instead of letting bad data propagate to dashboards and ML models. Tools with this capability can pause dbt runs, block table refreshes, or fail-fast on orchestrator DAGs based on test outcomes. Useful when downstream consumers cannot tolerate silently-incorrect data — financial reporting, regulated workflows, customer-facing surfaces.
