+/**
+ * DataContext implementation for Apache Cassandra database.
+ *
+ * When instantiating this DataContext, a keyspace name is provided. In
Cassandra,
+ * the keyspace is the container for your application data, similar to a
schema in
+ * a relational database. Keyspaces are used to group column families
together.
+ *
+ * This implementation supports either automatic discovery of a schema or
manual
+ * specification of a schema, through the {@link SimpleTableDef} class.
