### Redis Sentinel
Wild Duck is able to use Redis Sentinel instead of single Redis master for automatic failover. When using Sentinel and the Redis master fails then it might take a moment until new master is elected. Pending requests are cached during that window, so most operations should succeed eventually. You might want to test failover under load though, to see how it behaves.
Redis Sentinel failover does not guarantee consistency. Wild Duck does not store critical information in Redis, so even if some data loss occurs, it should not be noticeable.
