1.6.1. Syntax: ¶

The add basic syntax format of the command is as follows:

add key flags exptime bytes [noreply]
value

The parameters are described as follows:

• key :Key value key-value in the structure key used to find cached values

• flags :Can include integer parameters for key-value pairs, which clients use to store additional information about key-value pairs

• exptime :Length of time to save key-value pairs in the cache (in seconds,0 means forever)

• bytes :Number of bytes stored in the cache

• noreply (optional): this parameter tells the server that there is no need to return data

• value :The stored value (always in the second line) (which can be directly understood as key-value in the structure value )

1.6.2. Example ¶

In the following example, we set:

• Key → new_key

• Flag → 0

• Exptime → 900 (in seconds)

• Bytes → 10 (bytes of data storage)

• Value → data_value

add new_key 0 900 10
data_value
STORED
get new_key
VALUE new_key 0 10
data_value
END

1.6.3. Output ¶

If the data is added successfully, the output:

STORED

Output information description:

• STORED :Output after being saved successfully

• NOT_STORED :Output after a failed save
