Pipeline runs on schedule. Transitions from Draft, Paused, or Disabled via activate.
STATUS activeActive is the operational status in which the scheduler evaluates the pipeline's cron expression and triggers runs at the calculated next_run_at time. A pipeline enters the Active status through the activate operation (from Draft or Disabled) or the resume operation (from Paused). Activation validates that the pipeline contains non-empty SQL source and, when a schedule is present, a parseable cron expression. From Active, a pipeline can transition to Paused (temporary halt), Disabled (permanent stop), or remain Active while its lifecycle stage changes independently.
