Apache Spark reassigned SPARK-27627: ------------------------------------ Assignee: (was: Apache Spark) > Make option "pathGlobFilter" as a general option for all file sources > --------------------------------------------------------------------- > > Key: SPARK-27627 > URL: https://issues.apache.org/jira/browse/SPARK-27627 > Project: Spark > Issue Type: Improvement > Components: SQL > Affects Versions: 3.0.0 > Reporter: Gengliang Wang > Priority: Major > > Background: > The data source option "pathGlobFilter" is introduced for Binary file format: > https://github.com/apache/spark/pull/24354 , which can be used for filtering > file names, e.g. reading "*.png" files only while there is "*.json" files in > the same directory. > Proposal: > Make the option "pathGlobFilter" as a general option for all file sources. > The path filtering should happen in the path globbing on Driver. > Motivation: > Filtering the file path names in file scan tasks on executors is kind of > ugly. > Impact: > 1. The splitting of file partitions will be more balanced. > 2. The metrics of file scan will be more accurate. > 3. Users can use the option for reading other file sources. -- 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
