This library uses the http://hackage.haskell.org/package/cql[cql] library
which implements Cassandra's CQL protocol and complements it with the
neccessary I/O operations. The feature-set includes:

.Node discovery

The driver discovers nodes automatically from a small set of bootstrap nodes.

.Customisable load-balancing policies

In addition to pre-built LB policies such as round-robin, users of this
library can provide their own policies if desired.

.Support for connection streams

Requests can be multiplexed over a few connections.

.Customisable retry settings

Support for default retry settings as well as local overrides per query.

.Prepared queries

Prepared queries are an optimisation which parse and prepare a query only
once on Cassandra nodes but execute it many times with different concrete
values.

.TLS support

Client to node communication can optionally use transport layer security
(using HsOpenSSL).
