> 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).
