Description

The CQL native protocol is a binary frame-based protocol where each frame has a Header, a Length and a body. The protocol distinguishes Requests and Responses.

Some usage examples:

Constructing and Serialising a Request

let q = QueryString "select peer from system.peers where data_center = ? and rack = ?"
    p = QueryParams One False ("uk-1", "r-0") Nothing Nothing Nothing
    r = RqQuery (Query q p :: Query R (Text, Text) (Identity IP))
    i = mkStreamId 0
in pack V3 noCompression False i r

Deserialising a Response

-- assuming bh contains the raw header byte string and bb the raw
-- body byte string.
case header V3 bh of
    Left  e -> ...
    Right h -> unpack noCompression h bb

A generic query processing function

query :: (Tuple a, Tuple b) => Version -> Socket -> QueryString k a b -> QueryParams a -> IO (Response k a b)
query v s q p = do
    let i = mkStreamId 0
    sendToServer s (pack v noCompression False i (RqQuery (Query q p)))
    b <- recv (if v == V3 then 9 else 8) s
    h <- either (throwIO . MyException) return (header v b)
    when (headerType h == RqHeader) $
        throwIO UnexpectedRequestHeader
    let len = lengthRepr (bodyLength h)
    x <- recv (fromIntegral len) s
    case unpack noCompression h x of
        Left e              -> throwIO $ AnotherException e
        Right (RsError _ e) -> throwIO e
        Right response      -> return response

Synopsis

Cql type-class

class Cql a where Source #

A type that can be converted from and to some CQL Value.

This type-class is used to map custom types to Cassandra data-types. For example:

newtype MyType = MyType Int32

instance Cql MyType where
    ctype              = Tagged IntColumn
    toCql (MyType i)   = CqlInt i
    fromCql (CqlInt i) = Right (MyType i)
    fromCql _          = Left "Expected CqlInt"

Record/Tuple conversion. For example:

data Peer = Peer
    { peerAddr :: IP
    , peerRPC  :: IP
    , peerDC   :: Text
    , peerRack :: Text
    } deriving Show

recordInstance ''Peer

map asRecord <$> performQuery "SELECT peer, rpc_address, data_center, rack FROM system.peers"

The generated type-class instance maps between record and tuple constructors:

type instance TupleType Peer = (IP, IP, Text, Text)

instance Record Peer where
    asTuple (Peer a b c d) = (a, b, c, d)
    asRecord (a, b, c, d)  = Peer a b c d
