Memcached 面试题与答案
问题 11. How can you retrieve data from Memcached?
Data can be retrieved from Memcached using the 'get' command by providing the key associated with the desired value.
问题 12. Explain Memcached slabs and classes.
Memcached slabs represent chunks of memory allocated for items, and classes are sets of slabs with similar-sized items. Slabs are organized into classes to efficiently manage memory usage.
问题 13. What is Memcached replication?
Memcached replication involves creating copies of data on multiple Memcached servers. It provides redundancy and high availability in case a server goes down.
问题 14. How does Memcached handle cache misses?
In case of a cache miss, Memcached retrieves the data from the underlying storage (e.g., database) and stores it in the cache for subsequent requests.
问题 15. Explain Memcached memory optimization techniques.
Memory optimization in Memcached can be achieved through techniques like slab reassignment, adjusting item size, and optimizing key storage.
