What are the persistence features of Redis?

Redis offers two main persistence options: RDB (Redis Database Backup) and AOF (Append Only File). RDB creates snapshots of your dataset at specified intervals, while AOF logs every write operation received by the server.

How do RDB and AOF differ in terms of performance?

RDB is generally faster for recovery since it loads a single snapshot, but it can lead to data loss between snapshots. AOF, on the other hand, is slower for writes but provides better durability as it logs every operation.

Can I use both RDB and AOF together?

Yes, you can configure Redis to use both RDB and AOF. This way, you can benefit from the fast recovery of RDB and the durability of AOF.

What are the trade-offs of using AOF?

Using AOF can increase disk space usage and may slow down write operations, especially if you set the fsync policy to every write. However, it provides better data safety.
