- What are the underlying data structures of redis's five data types?
- Redis provides five data types, each type corresponds to a specific underlying data structure: String: Simple dynamic string (SDS), optimized binary safe string storage. Hash: Hash table (Dict), fast key-value pair storage. List: Doubly linked list or compressed list (Zip List), supports sequential access and insertion/deletion operations. Set: Integer set (IntSet) or hash table (Dict), unordered set, supports fast query and difference set operation. Ordered collection: Skip List, ordered collection, supports fast insertion, deletion and range query.

- What does redis lock mean?
- Redis lock is a distributed lock mechanism used to control access to shared resources and temporarily prevent concurrent processes from accessing resources at the same time through the SET/REDIS command. Its advantages include high performance, scalability, and ease of implementation. Can be used to limit concurrent access, prevent duplicate processing of queue messages, and ensure data consistency.

- What are the data types of redis
- Redis provides five basic data types: string, hash, list, set and ordered set to meet different data storage and processing needs. 1. Strings are used to store text data and support byte addressing and modification. 2. Hash stores key-value pairs, each key corresponds to a value, and the value can be of various data types. 3. The list stores an ordered list and supports fast tail insertion and deletion. 4. Collections store unique elements and support quick addition, deletion and search of elements. 5. An ordered set stores unique elements and sorts them by score, providing the function of querying and finding elements by score range.

- What are the characteristics of the five data types of redis
- Redis provides five data types: string (storing text or numbers), list (linked list structure, supports insertion and deletion), hash (key-value pair storage), set (unordered collection, no duplicate elements are allowed) and array Sorted set (ordered set, supports sorting and range queries). Each data type has unique characteristics and uses, for example strings can be used to store usernames and passwords, lists can be used to implement queue or FIFO (first in first out) messaging, hashes can be used to store user attributes, and sets can be used to store labels , and ordered sets can be used to implement leaderboards.
