Apache Spark commented on SPARK-18658: -------------------------------------- User 'NathanHowell' has created a pull request for this issue: https://github.com/apache/spark/pull/16089 > 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: Improvement > Components: SQL > Affects Versions: 2.0.2 > Reporter: 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
