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_columnslist of str, default None

Names of columns which should be dictionary encoded as they are read.

coerce_int96_timestamp_unitstr, default None.

Cast timestamps that are stored in INT96 format to a particular resolution (e.g. ‘ms’). Setting to None is equivalent to ‘ns’ and therefore INT96 timestamps will be infered as timestamps in nanoseconds.
