Redis uses a single core and shows better performance than Memcached in storing small datasets when measured in terms of cores. Memcached implements a multi-threaded architecture by utilizing multiple cores. Therefore, for storing larger datasets, Memcached can perform better than Redis.

Is memcached thread safe?

Memcached backend is not thread-safe.

What is memcache in cloud computing?

Memcached is an open source, distributed memory object caching system that alleviates database load to speed up dynamic Web applications. The system caches data and objects in memory to minimize the frequency with which an external database or API (application program interface) must be accessed.

What is memcache in Django?

Is memcache multi threaded?

Multithreaded architecture Since Memcached is multithreaded, it can make use of multiple processing cores. This means that you can handle more operations by scaling up compute capacity.

Is Lazy cache thread safe?

Lazy cache is a simple in-memory caching service. It has a developer friendly generics based API, and provides a thread safe cache implementation that guarantees to only execute your cachable delegates once (it’s lazy!).

How does memcache work?

When a client requests a data, Memcached checks for it in the cache. It returns the data if it is available in the cache. Otherwise, it queries the hard disk and then retrieves it. If there is any change in the data stored, the Memcached updates its cache to serve the latest data to the clients.
