Redis Append-Only Files vs Redis Replication

2023-04-10T05:21:12+00:00

Redis Append-Only Files (AOF) Redis Replication You can enable the Redis append-only file feature (AOF) for data durability. It is similar to creating manual backups. When enabled, the node writes all of the commands that change cache data to an append-only file.  When a node is rebooted and the cache engine starts, Redis goes through an AOF to replay the actions that were performed before the crash; the result is a warm Redis cache with all of the data intact. To enable AOF for a cluster running Redis, you must create a parameter group with the appendonly parameter set to [...]
