Storing Sorted Set in Redis: Insertion Commands
Explore how to store elements in Redis sorted sets using insertion commands such as ZADD. Understand how sorted sets are ordered by scores, and learn how to retrieve and count elements within specific score ranges to efficiently manage sorted data.
We'll cover the following...
Previously, we discussed how to store sets in the Redis database. The elements in the set are not stored in any specific order. If we need to store the elements in sorted order, we can use sorted sets, also known as ZSets, in Redis.
Now, the important thing to note is how the element will be sorted. Each element should be assigned a score before it is inserted into a sorted set. The Redis database sorts the elements in ascending order of this score.
The image below shows how elements are stored in ZSets. We have stored a set of all the countries, sorted based on their freedom of speech index.
