[jira] [Created] (SPARK-17059) Allow FileFormat to specify partition pruning strategy

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).
