>                 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).
