Caching Interview Questions

Top tools and frameworks using for Caching Data

1. Memcached

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.

2. Redis

Redis is free software, the data structure stored in memory, used as a broker for databases, caches, and messages. It actually supports data structures such as with strings, hashes, lists, sets, range query sorted sets, bitmaps, hyper logs, radius query and streams geospatial indexes.

3. Rabbitmq

RabbitMQ is an open-source message broker. It is used worldwide at small startups and large enterprises from T-Mobile to Runtastic. It is easily deployed on-premises and in the cloud that supports multiple messaging protocols because it is light weighted. RabbitMQ is running on many operating systems and cloud environments and provides a wide range of developer tools for the most popular languages. It gives a common safe platform for your applications to send and receive messages that act as an intermediary for messaging.
