Thanks for the comments. @fmcquillan99 Regarding MADLIB-1171. The following
commit about AO tables references this JIRA even though they are not related
https://github.com/madlib/madlib/commit/3db98babe3326fb5e2cd16d0639a2bef264f4b04.
It is very strange because the JIRA activity does not show that commit but it
has no trouble catching the mention your comment.
> 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
> Priority: Major
> Fix For: v2.0
>
> Attachments: model-versioning-work1.pdf, model-versioning-work2.pdf,
> p100.png, p101.png

> 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.
