-------------------------------------
Summary: Use more often the new parquet reader
Key: DRILL-5797
URL: https://issues.apache.org/jira/browse/DRILL-5797
Project: Apache Drill
Issue Type: Improvement
Components: Storage - Parquet
Reporter: Damien Profeta
The choice of using the regular parquet reader of the optimized one is based of
what type of columns is in the file. But the columns that are read by the query
doesn't matter. We can increase a little bit the cases where the optimized
reader is used by checking is the projected column are simple or not.
This is an optimization waiting for the fast parquet reader to handle complex
structure.
