Compression Formats

Athena supports the following compression formats:

  • SNAPPY (Default compression format for files in the Parquet format)

  • ZLIB. (Default compression format for files in the ORC format)

  • GZIP

  • LZO

    Note

    Use the GZIP compression in Athena for querying Amazon Kinesis Firehose logs. Athena and Amazon Kinesis Firehose each support different versions of SNAPPY, so GZIP is the only compatible format.
