set method in Memcached is used when storing data in Memcached using Ruby. It allows you to store a key-value pair in the cache, which can be later retrieved using the
get method. Common use cases are caching results from expensive database queries or storing session data.
Here's an example of how you can use the
set method in Memcached with Ruby:
In this example, we connect to the Memcached server running on localhost on port 11211. We then use the
set method to store the value 'value' with the key 'key'.
Another example could involve setting an expiration time for the cached data:
This example is similar to the previous one, but we've added an additional parameter to the
set method. The number 60 specifies that the key-value pair will expire and be removed from the cache after 60 seconds.
Memcached::ConnectionFailure, which need to be handled to prevent your application from crashing.
Can I store Ruby objects in Memcached?
Yes, Memcached can store Ruby objects. These objects will be serialized before being stored and deserialized when retrieved.
What happens when Memcached runs out of memory?
When Memcached runs out of memory, it uses a technique called LRU (Least Recently Used) to remove some old data and make room for new data.
