Andrew Duffy created SPARK-17059: ------------------------------------ Summary: Allow FileFormat to specify partition pruning strategy Key: SPARK-17059 URL: https://issues.apache.org/jira/browse/SPARK-17059 Project: Spark Issue Type: Bug Reporter: Andrew Duffy
Allow Spark to have pluggable pruning of input files for FileSourceScanExec by allowing FileFormat's to specify format-specific filterPartitions method. This is especially useful for Parquet as Spark does not currently make use of the summary metadata, instead reading the footer of all part files for a Parquet data source. This can lead to massive speedups when reading a filtered chunk of a dataset, especially when using remote storage (S3). -- 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
