Active Failover Limitations

The Active Failover setup in ArangoDB has a few limitations. Some of these limitations may be removed in later versions of ArangoDB:

  • Should you add more than one follower, be aware that during a failover situation the failover attempts to pick the most up to date follower as the new leader on a best-effort basis.
  • In contrast to full ArangoDB Cluster (with synchronous replication), there is no guarantee on how many database operations may have been lost during a failover.
  • Should you be using the ArangoDB Starter or the Kubernetes Operator to manage your Active-Failover deployment, be aware that upgrading might trigger an unintentional failover between machines.
