---------------------------------------
Summary: Support model versioning in output tables
Key: MADLIB-1171
URL: https://issues.apache.org/jira/browse/MADLIB-1171
Project: Apache MADlib
Issue Type: New Feature
Components: All Modules
Reporter: Frank McQuillan
Fix For: v2.0
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.
