I doubt if it is common enough to have an alias and document this in
`sql-programming-guide.md`. Other configurations like `parquet.page.size`,
`parquet.enable.dictionary` or `parquet.writer.version` are also rather
similarly used as much as that configuration in my experience.
I would add this for now.
