DataTable.to_parquet(path, compression=None, profile_name=None)[source]

Write DataTable to disk in the parquet format, location specified by path. Path could be a local path or a S3 path. If writing to S3 a tar archive of files will be written.


As the engine fastparquet cannot handle nullable pandas dtypes, pyarrow will be used for serialization to parquet.

  • path (str) – location on disk to write to (will be created as a directory)

  • compression (str) – Name of the compression to use. Possible values are: {‘snappy’, ‘gzip’, ‘brotli’, None}.

  • profile_name (str) – Name of AWS profile to use, False to use an anonymous profile, or None.
