pyarrow.dataset.ParquetReadOptions#
- class pyarrow.dataset.ParquetReadOptions(dictionary_columns=None, coerce_int96_timestamp_unit=None)#
Bases:
pyarrow.lib._Weakrefable
Parquet format specific options for reading.
- Parameters
- dictionary_columns
list
ofstr
, defaultNone
Names of columns which should be dictionary encoded as they are read.
