A haskell implementation of the memcahed protocol.
This implements the new binary protocol, so it only works with memcached version 1.3 and newer.
Example of usage, using the network package to obain a handle, and the OverloadedStrings language extension:
h <- connectTo "filename" $ UnixSocket "filename" hSetBuffering h NoBuffering con <- open h
set con "hello" "world" get con "hello"
In the above example we connect to a unix socket in the file "filename", set the key "hello" to the value "world" and then retrieve the value.
Operations are thread safe - multiple threads of execution may make concurrent requests on the memcahced connection.
Operations are blocking, but do not block other concurrent threads from placing requests on the connection.
- open :: Handle -> IO Connection
- close :: Connection -> IO ()
- data Connection
- type Key = ByteString
- type Value = ByteString
- type Result a = IO (Either (ResponseStatus, ByteString) a)
- data ResponseStatus
- set :: Connection -> Key -> Value -> Result ()
- get :: Connection -> Key -> Result ByteString
- delete :: Connection -> Key -> Result ()
- flush :: Connection -> Result ()
- stats :: Connection -> Result [(ByteString, ByteString)]
- version :: Connection -> Result ByteString
Create a connection. Please don't use the handle after opening a connection with it.
For thread safety of operations, we perform all requests on a wrapper around a handle.
Returns a list of stats about the server in key,value pairs
