Is memcached in-memory?
Unlike databases that store data on disk or SSDs, Memcached keeps its data in memory. By eliminating the need to access disks, in-memory key-value stores such as Memcached avoid seek time delays and can access data in microseconds. Memcached is also distributed, meaning that it is easy to scale out by adding new nodes.
What is Memcached and what does it do?
Memcached is an in-memory key-value store for small chunks of arbitrary data (strings, objects) from results of database calls, API calls, or page rendering. Memcached is simple yet powerful. Its simple design promotes quick deployment, ease of development, and solves many problems facing large data caches.
What does Memcached do in AWS ElastiCache cluster?
