FWIW, ActiveWarehouse has a Rails plugin on one side but it also has
an ETL Gem called, not surprisingly, ActiveWarehouse ETL. The
documentation is available here:

http://activewarehouse.rubyforge.org/docs/activewarehouse-etl.html

pretty easy to extend and that attempts to be idiomatic Ruby as much
as possible. Take a look and feel free to join the ActiveWarehouse
