How about the descriptions like the following (with extra info for users to make a suitable decision):
-
avro: (Default) Stores records in Avro format, which is row-based and ideal for streaming data and evolving schemas. -
parquet: Stores records in Apache Parquet format, which is column-based and optimized for analytical queries over large datasets.
