Hi All,
I wanted to experiment a little bit with TableScan and PrunedScan.
My first test was to print columns from various SQL queries.
To make this test easier, i just took spark-csv and i replaced TableScan
with PrunedScan.
I then changed buildScan method of CsvRelation from
def BuildScan
Hi Gil
You would need to prune the resulting Row as well based on the requested
columns.
