For life‐critical systems, high fault‐tolerance is required. In streaming computing environments, where unbounded data are generated in real‐time, an amazing high adaptation to noncritical failure procedure and scalable system, is required to allow an application to keep working without interruption despite component failure. The most widely recognized adaptation to internal failure is checkpointing, where the framework state is intermittently persisted to recapture the computational state after system failures. However, the overhead incurred with checkpointing can negatively affect system performance. An improved checkpointing to minimize the overhead cost was proposed by [28, 29].
