Summary

Redis is an advanced key-value store. It is often referred to as a data

structure server since keys can contain strings, hashes, lists, sets and

sorted sets.

You can run atomic operations on these types, like appending to a string;

incrementing the value in a hash; pushing to a list; computing set

intersection, union and difference; or getting the member with highest

ranking in a sorted set.

In order to achieve its outstanding performance, Redis works with an

in-memory dataset. Depending on your use case, you can persist it either

by dumping the dataset to disk every once in a while, or by appending

each command to a log.

Redis also supports trivial-to-setup master-slave replication, with very

fast non-blocking first synchronization, auto-reconnection on net split

and so forth.

Other features include Transactions, Pub/Sub, Lua scripting, Keys with a

limited time-to-live, and configuration settings to make Redis behave like

a cache.

You can use Redis from most programming languages also.
