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.
