Final answer:
The recovery mechanism called a full restart or checkpoint restart allows jobs to be rerun from the beginning without relying on a previous partial rerun. It's beneficial for jobs without clear checkpointing or when a clean state is necessary to ensure consistency.
Step-by-step explanation:
The recovery mechanism that allows you to rerun jobs without a previous partial rerun is known as a full restart or checkpoint restart.
When a job fails, this approach does not attempt to continue from the point of failure; instead, it restarts the entire job from the beginning.
In contrast, a partial restart or incremental recovery would attempt to resume the job from the last successful checkpoint or saved state.
The full restart approach is beneficial when jobs have no clear checkpointing mechanism, or when the partial state is not trustworthy and could lead to inconsistencies if processing continued from that point.
Job schedulers and workflow management systems often include features for both full and partial restarts, allowing administrators or developers to configure the preferable recovery strategy based on the nature of the task and the acceptable balance between performance and reliability.
