[jira] [Created] (DRILL-6940) CTAS partition parquet file with non existant columns

benj created DRILL-6940:
---------------------------

             Summary: CTAS partition parquet file with non existant columns
                 Key: DRILL-6940
                 URL: https://issues.apache.org/jira/browse/DRILL-6940
             Project: Apache Drill
          Issue Type: Improvement
          Components: Metadata, Storage - Parquet
    Affects Versions: 1.14.0
            Reporter: benj


Drill allows to create parquet files with partition and metadata that allow potential pruning.

Currently the "PARTITION BY" can only apply on present-column.

It will be useful to have the possibility to allow PARTITION BY on "non-present data" or "computed data"

Examples :
 * I have a,b and c, and I want to put only "b" and "c" in the parquet but partition on "a"
 * I have a,b and c, and I want to put "a", "b" and "c" in the parquet and partition NOT on a but on myfct(a)
