What are the differences between Redis persistence options?

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. This means AOF can provide more durability but may use more disk space.

Which one is better for performance?

Generally, RDB is faster for read operations since it loads data from a snapshot, while AOF can be slower due to the overhead of logging every write. However, the best choice depends on your specific use case and requirements for durability versus performance.

What about data recovery?

AOF provides better data recovery options since it logs every operation, allowing you to recover data up to the last write. RDB, on the other hand, may result in some data loss if a failure occurs between snapshots.

Can I use both persistence methods together?

Yes, you can configure Redis to use both RDB and AOF simultaneously. This way, you can benefit from the advantages of both methods, ensuring better durability and faster recovery.
