When Batch Reruns Spiral: Solving GBase 8a's Hidden Transaction Design Problem

GBase 8a batch failures stem not from scheduling, but from unclear transaction commit strategies and boundaries. When jobs fail midway, teams face an impossible choice: reruns risk duplicating results or leaving stale data, forcing manual recovery. Explicit batch identifiers, idempotent job design, and well-defined transaction boundaries are critical to building self-recovering batch pipelines that operators can trust.
