haskell haskell@gentoo.org 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. This library is a Haskell client for the Redis datastore. Compared to other Haskell client libraries it has some advantages: [Complete Redis 2.6 command set:] All Redis commands (<http://redis.io/commands>) are available as haskell functions, except for the MONITOR and SYNC commands. Additionally, a low-level API is exposed that makes it easy for the library user to implement further commands, such as new commands from an experimental Redis version. [Automatic Optimal Pipelining:] Commands are pipelined (<http://redis.io/topics/pipelining>) as much as possible without any work by the user. See <http://informatikr.com/2012/redis-pipelining.html> for a technical explanation of automatic optimal pipelining. [Enforced Pub\/Sub semantics:] When subscribed to the Redis Pub\/Sub server (<http://redis.io/topics/pubsub>), clients are not allowed to issue commands other than subscribing to or unsubscribing from channels. This library uses the type system to enforce the correct behavior. [Connect via TCP or Unix Domain Socket:] TCP sockets are the default way to connect to a Redis server. For connections to a server on the same machine, Unix domain sockets offer higher performance than the standard TCP connection. For detailed documentation, see the "Database.Redis" module. [Changes since version 0.5] * New commands: DUMP, RESTORE, BITOP, BITCOUNT. * Removed the dependency on stm. * Improved performance of Queued in long transactions. * Minor documentation updates. [Changes since version 0.4.1] * Added new Redis 2.6 commands, including Lua scripting support. * A transaction context is now created by using the 'multiExec' function. The functions 'multi', 'exec' and 'discard' are no longer available individually. * Inside of a transaction, commands return their results wrapped in a composable /future/, called 'Queued'. * The 'getType' command (the Redis TYPE command) now has a custom return type 'RedisType'. * Minor improvements and fixes to the documentation.
