Can you explain how Redis handles failover?
Redis uses a master-slave replication model for failover. If the master fails, a slave can be promoted to master.
What happens during a failover process?
During failover, Redis detects the master failure, promotes a slave, and reconfigures the remaining slaves to replicate from the new master.
Is there any downtime during this process?
There might be a brief downtime during the failover, but Redis aims to minimize this with its automatic detection and promotion.
How can I configure Redis for high availability?
You can configure Redis Sentinel for high availability, which monitors master and slave instances and manages failover.
