It is open-source, networked, in-recollection, and stores keys with optional durability. When the durability of data is not needed, the in-recollection nature of Redis sanctions it to perform astronomically well compared to database systems that indite every transmutation to disk afore considering a transaction committed. Redis is commonly deployed on IaaS or PaaS platforms like Amazon Web Accommodations, Rackspace, or Heroku. Many languages have Redis bindings, including: ActionScript, C, C++, C#, Clojure, Prevalent Lisp, Dart, Erlang, Go, Haskell, Haxe, Io, Java, JavaScript (Node.js), Lua, Objective-C, Perl, PHP, Pristine Data, Python, R, Ruby, Scala, Smalltalk and Tcl. Following is the trend analysis of databases.
