> Most of the data formats on HDFS don't support projecting specific columns.
> For such formats we can still avoid resolving every individual field in the
> record and instead only resolve fields that need to be projected and send
> NULLs for other fields.
> This task specifically focusses on improving the performance of Hive PXF
> profile which positively impacts both Hive and HiveORC profile
