Apache Spark reassigned SPARK-26081: ------------------------------------ Assignee: (was: Apache Spark) > Do not write empty files by text datasources > -------------------------------------------- > > Key: SPARK-26081 > URL: https://issues.apache.org/jira/browse/SPARK-26081 > Project: Spark > Issue Type: Improvement > Components: SQL > Affects Versions: 2.4.0 > Reporter: Maxim Gekk > Priority: Minor > > Text based datasources like CSV, JSON and Text produces empty files for empty > partitions. This introduces additional overhead while opening and reading > such files back. In current implementation of OutputWriter, the output stream > are created eagerly even no records are written to the stream. So, creation > can be postponed up to the first write. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
