What data storage organization methods are used in Redis?

Redis supports several data storage methods that allow efficient handling of different data types:

• Strings — the basic type that can store text or binary data.
• Lists — ordered collections of strings, supporting addition and removal operations from both ends.
• Sets — unordered collections of unique strings, useful for intersection, union, and difference operations.
• Sorted Sets — sets with unique elements, each having a numeric score for sorting.
• Hashes — structures similar to dictionaries, where key-value pairs can be stored.
• Bitmaps and HyperLogLogs — specialized structures for working with bits and counting unique elements.

Additionally, Redis supports various mechanisms for persisting data to disk: RDB (database snapshots) and AOF (append-only file), which provide a balance between performance and data safety.
