Let's imagine a web application, where for each request received, it must read some configuration data of a database. That data doesn't change usually, but the application, in each request, must connect, execute the correct instructions to read the data, pick it up from the network, etc. What would happen?

Redis , short for Remote Dictionary Server, is a BSD-licensed, open-source in-memory key-value data structure store written in C language by Salvatore Sanfillipo and was first released on May 10, 2009. Depending on how it is configured, Redis can act like a database, a cache or a message broker. Data Structures in Redis.
