> Project: Spark
> Issue Type: Sub-task
> Components: ML
> Affects Versions: 2.3.0
> Reporter: Weichen Xu
>
> We add a parameter indicating whether to persist models to disk during training (default = off). This will use ML persistence to dump models to a directory so they are available later but do not consume memory.
> Note: when persisting the model list, use indices as the sub-model path
