Description

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.
