| Hazelcast stores Jet job state in distributed map objects and uses their backup configuration for replication. | ||
| During a split-brain, the primary partition and all its backups may end up in the same (smaller) sub-cluster, | ||
| leaving the larger one without the required snapshot data and causing the job restart to fail. | ||
| To reduce this risk, increase the number of job backups. |
