Richard Williamson updated SPARK-8992:
--------------------------------------
Description:
SQLServer and other databases provide capabilities to transpose data from columns to rows and rows to columns, the later is very useful for analytic use cases like turning rows into feature columns for an MLlib model. Here is a reference for the SQLServer implementation: http://sqlhints.com/2014/03/10/pivot-and-unpivot-in-sql-server/
