Redis

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.


* Admin Package included: OpenVPN, SSH, SFTP, OS root access

Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache and message broker.

It supports data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs and geospatial indexes with radius queries.

Redis has built-in replication, Lua scripting, LRU eviction, transactions and different levels of on-disk persistence, and provides high availability via Redis Sentinel and automatic partitioning with Redis Cluster.

You can run atomic operations on these types, like appending to a string; incrementing the value in a hash; pushing an element 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.

Persistence can be optionally disabled, if you just need a feature-rich, networked, in-memory cache.

Redis also supports trivial-to-setup master-slave asynchronous replication, with very fast non-blocking first synchronization, auto-reconnection with partial resynchronization on net split.

Other features include:

  • Transactions
  • Pub/Sub
  • Lua scripting
  • Keys with a limited time-to-live
  • LRU eviction of keys
  • Automatic failover

You can use Redis from most programming languages out there.

Redis is written in ANSI C and works in most POSIX systems like Linux, *BSD, OS X without external dependencies.
