    Description

      This article suggests that better generated code can improve performance by facilitating compiler optimizations.
      This JIRA changes the generated code for sqlContext.read.parquet("file") to facilitate loop optimizations in a JIT compiler for achieving better performance. In particular, this stackoverflow entry suggests me to improve performance of sqlContext.read.parquet("file").count}.
