get function in a Python Memcached client is primarily used for retrieving data (values) using respective keys. Common use cases include caching data to reduce database load, storing session data, or rapid retrieval of frequently accessed information.
Let's assume you're using the
pymemcache library, which is a comprehensive Python client for Memcached.
Firstly, install pymemcache with pip:
Then, here's an example of how to use the get method:
In this code, we first create a connection to our Memcached server running on localhost at port 11211. Then we store a value 'my_value' under the key 'my_key'. After that, we retrieve the stored value using the
get function and print it.
get. If the key doesn't exist in the cache,
getwill return None.
get_multito perform them in one network call.
What happens if I try to
get a key that doesn't exist?
getmethod will return None.
Is there any difference between
getretrieves a single key-value pair, while
get_multican retrieve multiple key-value pairs in a single call, optimizing network usage.
