> Context
> For many MADlib modules, <out_table> contains the separate models for each
> group and <out_table>_summary contains the common model data for all groups.
> Modeling versioning can be awkward since the model output table and model
> summary table need to be explicitly dropped between runs.
> Story
> As a data scientist, I want to perform multiple runs without having to drop
> tables, so that I can easily get a history of the model runs with clear
> versioning.
