Securing high availability in a shared-nothing architecture
1. The failed node leaves the cluster due to some hardware failure or a rolling upgrade.
3. CrateDB performs an automatic failover, where all the data remain available on the other nodes.
3. As the new node joins, automatic data synchronization and rebalancing take place.
4. Once the new node is part of the system and data are fully replicated again, the self-healing process is completed.
