Redshift Re-exports
data RedshiftT (m :: Type -> Type) a #
The Redshift monad transformer that all the redshift API operations run in. This monad ensures that all tunnels get a unique port on localhost.

connectRedshift :: forall (m :: Type -> Type). MonadIO m => RedshiftDB -> Int -> NominalDiffTime -> Int -> RedshiftT m (Pool Connection) #
Establish a postgresql-simple connection to a RedshiftDB.
runRedshift :: MonadIO m => RedshiftState -> RedshiftT m a -> m a #
Runs any DB action in IO.
The only way to unwrap RedshiftT, as we need to carefully manage SSH tunnels and database connections.
defRS :: Configuration -> RedshiftState #
A default RedshiftState that cleans up and is not verbose. If you
store your keys in ~/.aws-keys you can use baseConfiguration
for
the configuration parameter
redNick :: String -> IO RedshiftDB #
Retrieves a RedshiftDB for the specified DB nickname.
withRedshift :: String -> Int -> NominalDiffTime -> Int -> (BackendConn Redshift -> IO b) -> IO b #
withPostgresString :: Natural -> String -> (BackendConn Redshift -> IO b) -> IO b #
