The hedis package
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 0.5.1
Changed return type of HDEL from Bool to Integer.
Some documentation updates.
- 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.
