Impact

During the upgrade window: Some jobs may experience failover due to node migration or restarts. After failover, jobs will be automatically recovered based on their configured restart strategy. We strongly recommend setting your job’s restart strategy to "restart" to ensure automatic recovery. If the restart strategy is set to "none", the job will not resume after failover and must be manually restarted. The console and APIs will remain accessible during the maintenance period. You can log in, view job status, and manually restart jobs as needed.

Recommendation

To minimize potential impact, we recommend that you:

1. Verify your job’s restart strategy is set to "restart".
2. Monitor your critical jobs during the maintenance window.
3. Proactively restart non-critical jobs before the upgrade if necessary.
