[jira] [Created] (SPARK-14467) Add async io in FileScanRDD

Nong Li created SPARK-14467:
-------------------------------

             Summary: Add async io in FileScanRDD
                 Key: SPARK-14467
                 URL: https://issues.apache.org/jira/browse/SPARK-14467
             Project: Spark
          Issue Type: Improvement
          Components: SQL
            Reporter: Nong Li


Experiments running over parquet data in s3 shows poorly interleaving of CPU and IO. We should do more async IO in FileScanRDD to better use the machine resources.
