ActiveWarehouse ETL 0.6.0 has been released. A bit of background: ActiveWarehouse ETL is an open source (MIT licensed) Ruby library which supports the Extract-Transform-Load process that is typically required by data warehouse developers. It is part of the ActiveWarehouse project which is a plugin for Ruby on Rails which makes it easy to develop data warehouses on Rails. More information on ActiveWarehouse ETL and ActiveWarehouse in general can be found at [http://activewarehouse.rubyforge.org/](http://activewarehouse.rubyforge.org/) This release is a pretty significant one as the ETL component of ActiveWarehouse has been put through its paces quite a bit recently. This release includes a slew of new features and enhancements, including support for row-level processing/transforming, both after load and before write, new transforms like the HierarchyLookupTransform and the DefaultTransform, improved interface for transformations, an Apache Combined Log parser, improvements to the SAX parser, timestamped log files, automatic timestamped local storage of source data if it is extracted from a database for auditing, a :conditional option in destinations which can be supplied a proc and which can determine if a row should be written, a simple control-file dependency declaration and a bunch of other fixes and minor improvements. This release should be up on the RubyForge gem mirrors within an hour, or you can get it from the ActiveWarehouse files section at [http://rubyforge.org/frs/?group\_id=2435](http://rubyforge.org/frs/?group_id=2435) on RubyForge.
