Redis Interview Questions

Memcached Interview Questions

Memcached is a memory caching system used to optimize dynamic database-driven webpages by caching data in RAM to minimize the memory calls to external data. It is free and open-source software, licensed under the Revised BSD license, and runs on Unix-like operating systems and on Microsoft Windows and also, it depends on the lib-event library.

Memcached's APIs supply a very huge hash table distributed across various machines and when the table is full, subsequent inserts cause older data to be purged in the least recently used (LRU) order in addition to that, applications using Memcached typically layer requests and additions into RAM before falling back on a slower backing store.

Rabbitmq Interview Questions
