Redis five basic data types

Redis provides five basic data types: strings, hashes, lists, sets and ordered sets, which are suitable for different data storage scenarios. These types support a variety of operations such as storage, modification, deletion, sorting, and querying. They provide developers with flexible and effective data management solutions.

Five basic data types in Redis

Redis provides five basic data types, which are:

• String (String)
• Hash (Hash)
• List (List)
• Set (set)
• ZSet (ordered set)

##String (String)

The simplest data type, which can store any byte sequence.
• Suitable for situations where text or binary data needs to be stored.
• Supports various operations, such as append, replace, length acquisition, etc.

Hash (Hash)

An associative array containing key-value pairs.
• The key is a string, and the value can be a string, hash, list, etc.
• Suitable for storing objects or structured data.
• Supports various operations, such as getting, setting, and deleting key-value pairs.

List (list)

An ordered queue, the elements can be of any type.
• Supports operations such as entering and exiting the queue, obtaining elements, and pruning.
• Suitable for storing collections that need to be processed in order, such as task queues.

Set (set)

An unordered collection of elements, each element is unique.
• Support operations such as addition, deletion, intersection, and union.
• Suitable for storing set data or calculating intersection and union.

ZSet (Ordered Set)

An ordered set where each element has an associated score.
• Supports operations such as ordered sorting, obtaining rankings, and range queries.
• Suitable for storing data that needs to be sorted by score, such as rankings.
