Redis is an in-memory database with a simple key value data structure ( English key value store ) and belongs to the NoSQL database family (it is therefore not relational ). redis is open source and, according to a survey by DB-Engines.com, the most common key-value store .

The simple structure of the database is less suitable for complex data structures that are mainly to be mapped in the database itself. On the other hand, the big advantage of Redis is that it is faster than relational databases such as B. MySQL .

From version 2.6 Lua scripts are supported. From version 3.0 it is possible to use Redis distributed in clusters . Version 3.2 introduces a GEO API.

Redis offers persistence through automated, regular storage or via log file, whereby ACID- compliant durability can also be achieved with the appropriate configuration .

Surname

The name Redis originated as an abbreviation for English remote dictionary server .
