Weichen Xu commented on SPARK-27534: ------------------------------------ I am working on this. :) > Do not load `content` column in binary data source if it is not selected > ------------------------------------------------------------------------ > > Key: SPARK-27534 > URL: https://issues.apache.org/jira/browse/SPARK-27534 > Project: Spark > Issue Type: Story > Components: SQL > Affects Versions: 3.0.0 > Reporter: Xiangrui Meng > Assignee: Weichen Xu > Priority: Major > > A follow-up task from SPARK-25348. To save I/O cost, Spark shouldn't attempt > to read the file if users didn't request the `content` column. For example: > {code} > spark.read.format("binaryFile").load(path).filter($"length" < 1000000).count() > {code} -- 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
