ColumnMapper

trait ColumnMapper[T] extends Serializable

Produces ColumnMap objects that map class T properties to columns in a given Cassandra table.

You can associate a custom ColumnMapper object with any of your classes by providing an implicit ColumnMapper in the companion object of the mapped class:

CREATE TABLE kv(key int primary key, value text);
case class KeyValue(k: Int, v: String)

object KeyValue {
  implicit val columnMapper =
    new DefaultColumnMapper[KeyValue](Map("k" -> "key", "v" -> "value"))
}
