Drill + Evolving Parquet Schema

Let's say I have one parquet file per day, one row per host.  Each column is a metric for that host.




Drill can scan over many days of files and use them fine.

What if I add and/or remove columns to the newer files over time though.  Can drill deal with looking up "cpu" when some of the files don't have CPU, etc?
