What happens during a Redis clustering failover?
During a Redis clustering failover, if a master node fails, one of the replicas is promoted to master to ensure availability.
How does Redis determine which replica to promote?
Redis uses a voting mechanism among replicas to elect a new master, considering factors like replication lag.
What are the potential issues during a failover?
Potential issues include data inconsistency, increased latency, and the risk of split-brain scenarios if not configured properly.
Can I configure automatic failover in Redis?
Yes, you can configure automatic failover using Redis Sentinel, which monitors master and replica nodes.
