Redis is an open source, 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.
