>                 Key: SPARK-18658
>                 URL: https://issues.apache.org/jira/browse/SPARK-18658
>             Project: Spark
>          Issue Type: Sub-task
>          Components: SQL
>    Affects Versions: 2.0.2
>            Reporter: Nathan Howell
>            Assignee: Nathan Howell
>            Priority: Minor
>
> The JSON and CSV writing paths buffer entire lines (or multiple lines) in 
> memory prior to writing to disk. For large rows this is inefficient. It may 
> make sense to skip the {{TextOutputFormat}} record writer and go directly to 
> the underlying {{FSDataOutputStream}}, allowing the writers to append 
> arbitrary byte arrays (fractions of a row) instead of a full row.
