What are the different types of data structures supported by Redis?

The data structures in Redis mainly consist of the following categories:

1. String: the most basic data structure that can store text, numbers, and other types of data.
2. List: a doubly linked list that can store multiple elements and supports inserting and deleting elements at both ends.
3. Set: an unordered collection of strings in which duplicate elements are not allowed.
4. Sorted set: Similar to a set, but each element is associated with a score and sorted according to the score.
5. Hash table: similar to an associative array, it stores the mapping relationship between fields and their corresponding values.
6. HyperLogLog is used for probabilistic cardinality estimation to provide an approximate count of unique elements in a set.
7. Geospatial indexing is used to store geographic location information and allows for calculating location relationships based on distance and coordinates.
