What are the data types of redis

Redis provides five basic data types: strings, hashes, lists, sets and ordered sets 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.

Redis’ data types

Redis provides a variety of data types to meet different data storage and processing needs . These types can be divided into five basic types:

1. String

• The most basic data type, used to store text data.
• Supports byte addressing and modification to facilitate string operations.

2. Hash

• Dictionary structure, used to store key-value pairs.
• Each key corresponds to a value, which can be a string, number or other data type.

3. List

• linked list structure, used to store ordered lists.
• Elements can be accessed in insertion order, supporting fast tail insertion and deletion.

4. Set

• Unordered collection, used to store unique elements.
• Supports quickly adding, deleting and finding elements.

5. Ordered set

• Ordered set is used to store unique elements and sort them by score.
• Provides the function of querying and finding elements by score range.
