pyarrow.parquet.write_table

pyarrow.parquet.write_table(table, where, row_group_size=None, version='1.0', use_dictionary=True, compression='snappy', use_deprecated_int96_timestamps=None, coerce_timestamps=None, allow_truncated_timestamps=False, flavor=None, **kwargs)[source]

Write a Table to Parquet format

Parameters:
  • table (pyarrow.Table) –
  • where (string or pyarrow.NativeFile) –
  • version ({"1.0", "2.0"}, default "1.0") – The Parquet format version, defaults to 1.0
  • use_dictionary (bool or list) – Specify if we should use dictionary encoding in general or only for some columns.
  • use_deprecated_int96_timestamps (boolean, default None) – Write nanosecond resolution timestamps to INT96 Parquet format. Defaults to False unless enabled by flavor argument
  • coerce_timestamps (string, default None) – Cast timestamps a particular resolution. Valid values: {None, ‘ms’, ‘us’}
  • allow_truncated_timestamps (boolean, default False) – Allow loss of data when coercing timestamps to a particular resolution. E.g. if microsecond or nanosecond data is lost when coercing to ‘ms’, do not raise an exception
  • compression (str or dict) – Specify the compression codec, either on a general basis or per-column. Valid values: {‘NONE’, ‘SNAPPY’, ‘GZIP’, ‘LZO’, ‘BROTLI’, ‘LZ4’, ‘ZSTD’}
  • flavor ({'spark'}, default None) – Sanitize schema or set other compatibility options for compatibility
