------------------------------------
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).
