What type of data persistence does Redis support?
Redis supports several types of data persistence, including:
- RDB persistence: periodically saving data from memory to disk at specified time intervals to create a snapshot file. By default, Redis checks every 60 seconds to see if persistence is required, and if so, it initiates the persistence process.
- AOF persistence: Appending write commands executed by Redis to the end of a file to keep track of data changes. Upon Redis restart, data can be restored by re-executing the commands in the AOF file.
Users have the option to choose between using RDB persistence, AOF persistence, or a combination of both to ensure data durability.
