[jira] [Created] (SPARK-11787) Speed up parquet reader for flat schemas

Nong Li created SPARK-11787:
-------------------------------

             Summary: Speed up parquet reader for flat schemas
                 Key: SPARK-11787
                 URL: https://issues.apache.org/jira/browse/SPARK-11787
             Project: Spark
          Issue Type: Task
          Components: SQL
            Reporter: Nong Li


Measuring the performance of running some of the TPCDS and anecdotally, parquet scan and record reconstruction performance is a bottleneck.

For simple schemas, we can do better using the lower level parquet-mr APIs.
