Amazon Athena supports a variety of file formats for querying data stored in Amazon S3, including CSV, TSV, JSON, Parquet, ORC, Avro, and Apache Arrow. It also supports compressed formats such as GZIP, BZIP2, Snappy, LZO, and Zstandard. For optimal query performance and cost efficiency, columnar formats like Parquet, ORC, and Avro are recommended because they enable efficient compression and predicate pushdown.
