parquet file
URL: https://github.com/apache/drill/pull/1298#issuecomment-404524244
 
 
   @jbimbert Drill usually 
   - puts a single space between `if` and `(` or between `switch` and `(`.
   - use single space only
   Please try to fix all newly introduced occurrences that do not comply with 
the formatting agreement
   
   @arina-ielchiieva Without drill checkstyle enforcing common formatting, you 
may need to point all cases that do not comply with the preferred formatting 
and need to be fixed.

> Today, filter pruning use the file name as the partitioning key. This means 
> you can remove a partition only if the whole file is for the same partition. 
> With parquet, you can prune the filter if the rowgroup make a partition of 
> your dataset as the unit of work if the rowgroup not the file.
