Script Development / Connector Object DFF.CONN / Memcached

The Memcached Connector operation object primarily provides Memcached operation methods.

The DFF.CONN(...) parameters are as follows:

Parameter	Type	Required / Default	Description
connector_id	str	Required	Connector ID

.query(...)

Calls the specified method in the python-memcached client. .query(...) is an alias of .run(...), and command names are case-insensitive.

Parameter	Type	Required / Default	Description
command	str	Required	The python-memcached client method name, e.g., GET, SET
*args	-	-	Positional arguments passed to the client method
**kwargs	-	-	Named arguments passed to the client method

db.query('SET', 'myKey', 'myValue')
result = db.query('GET', 'myKey')
# 'myValue'

The return value is consistent with the corresponding python-memcached client method.

Convenience Methods

The Connector also provides the following convenience methods:

Method	Description
.get(key)	Gets the value of a key
.set(key, value)	Sets the value of a key
.add(key, value)	Sets only if the key does not exist
.replace(key, value)	Replaces only if the key exists
.delete(key)	Deletes a key

These methods all call .run(...) internally, and their return values match the corresponding python-memcached methods. When you need to pass additional parameters such as expiration time, you can use .query(...) or .run(...) to directly call the client method.
