Let's move on to learning the basic Redis commands. To use them, open the Redis CLI using the command: redis-cli, making sure that the Redis server is running first.

SET Command

The SET command is used to store a key-value pair in Redis. If the key already exists, its value will be overwritten with the new one.

A key is a unique name under which a value will be stored in Redis. The value represents the data you want to save, and it can be a string, number, JSON, or another data format.

Example Usage

Suppose we want to create a key named mykey and store a specific value in it. Using the syntax above, we can execute:

As a result, Redis creates a record where the key is mykey and the value is the string Hello, Redis!. If the key mykey already existed, its previous value would be replaced with the new one.
