Assignee: Kalyan
> HFile support for SparkSQL DataFrame saves
> ------------------------------------------
>
> Key: PHOENIX-2938
> URL: https://issues.apache.org/jira/browse/PHOENIX-2938
> Project: Phoenix
> Issue Type: Improvement
> Reporter: Chris Tarnas
> Assignee: Kalyan
> Priority: Minor
>
> Currently when saving a DataFrame in Spark it is persisted as upserts. Having
> an option to do saves natively via HFiles, as the MapReduce loader does,
> would be a great performance improvement for large bulk loads. The current
> work around to reduce the load on the regionservers would be to save to csv
> from Spark then load via the MapReduce loader.
