[jira] [Updated] (SPARK-18658) Writing to a text DataSource buffers one or more lines in memory

Reynold Xin updated SPARK-18658:
Affects Version/s: (was: 2.0.2)
> Writing to a text DataSource buffers one or more lines in memory
>
>
> Key: SPARK-18658
> URL: https://issues.apache.org/jira/browse/SPARK-18658
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
>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.
