Here is the documentation for Spark configuration options: https://spark.apache.org/docs/3.5.5/configuration.html

And here are options for Parquet:
https://spark.apache.org/docs/3.5.5/sql-data-sources-parquet.html
You can also find other formats' options in the list on the left.

The links are for 3.5.5, but I assume they'll be the same or similar for the older/newer versions.
