About Redis

Redis is open-source software that allows the user to store and maintain a persistent and durable database. Redis has the enormous advantage of supporting a Lua interpreter, meaning that one can write code in tons of languages, such as Perl, Python, Java, C, C++, Ruby, among many others. Redis was developed mainly by a single programmer, which is something to admire. His name is Salvatore Sanfilippo, who is sponsored and supported entirely by Redis Labs, hence the name of the database software. It was launched around August of 2009, and the team has since expanded to include other proficient programmers of Redis Labs, such as Pieter Noordhuis.

Redis works in a very particular way that opens up its applications to many industries, such as gaming, financial services, media-streaming, among many other useful applications that help Snapchat, Twitter, among many other notable technology companies run smoothly. Redis has significant applications in any industry that involves the quick retrieval of data. This software has seen a recent rise in its application for Machine Learning in fraud detection. Online fraud happens extremely quickly, and Redis is one of the quickest readers on information in the entire database developer landscape. Redis is used alongside other technologies to help computers learn and detect fraud and abnormalities at speeds and accuracies not possible before.

Redis has some characteristics that make it good for all of the above fields. First, one must consider that Redis stores the data almost entirely in the server's main memory, which means that data requests do not have to loop back and forth with the server and client. This has the result of achieving incredibly fast response times and the capacity of making tens of millions of operations in very short periods of time. Even advanced and newer technologies like MongoDB or Cassandra cannot achieve this level of efficiency, although they make up for it with other advantages. Nevertheless, for the user needing maximum speed of writing and retrieving data, Redis is the best choice.


The first release of Redis was made available to the public in August of 2009. It was around this time that much NoSQL software like MongoDB or Cassandra was launched, indicating that the technology is booming and has very applicable features, which can still evolve rapidly due to the NoSQL wave being so young. We are currently on the 6.2.3 stable version of Redis, launched on May 3 of 2021. Redis releases are separated into candidate branches, where there are experimental stable releases, release candidates which then go into the widely used stable releases when approved.
