Cequel records can have parent-child relationships defined byand associations. Unlike in a relational database ORM, associations are not represented by foreign keys; instead they use CQL3's compound primary keys. A child object's primary key begins with it's parent's primary key.
In the below example, the `blogs` table has a one-column primary key `(subdomain)`, and the `posts` table has a two-column primary key `(blog_subdomain, permalink)`. All posts that belong to the blog with subdomain `“cassandra”` will have `“cassandra”` as their `blog_subdomain`.
