Review comment:
Maybe "metadataColumn" or "implicitColumns"? From a pure implementation
perspective, every column is a schema column for some schema. Please pick a
name that explains their use: "statisticsColumns"?
And, thank you for renaming this. I would have guessed that
"excludedColumns" were those in the file that are not being projected in this
query, which would then have seemed very odd.
