Overview

A collection type that allows you to store key/value pairs in Cassandra. Changes are tracked by hooking into ActiveModel’s built-in change tracking.

Keys are converted to have the name of the collection prefixed to them as this is how the Solr/Cassandra integration converts between them and dynamic fields.
