Summary : A persistent key-value database
URL : http://redis.io
License : BSD
Description : 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.
