[jira] [Updated] (ARROW-11464) [Python] pyarrow.parquet.read_pandas
doesn't conform to its docs
[ https://issues.apache.org/jira/browse/ARROW-11464?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Pac A. He updated ARROW-11464:
------------------------------
Description:
The {{*pyarrow.parquet.read_pandas*}} [implementation|https://github.com/apache/arrow/blob/816c23af4478fe28f31d474e90b433baeadb7a78/python/pyarrow/parquet.py#L1740-L1754] doesn't conform to its [docs|https://arrow.apache.org/docs/python/generated/pyarrow.parquet.read_pandas.html#pyarrow.parquet.read_pandas] in at least these ways:
# The docs state that a *{{filesystem}}* option can be provided, as it should be. Without this option I cannot read from S3, etc. The implementation, however, doesn't have this option! As such I currently cannot use it to read from S3!
# The docs state that the default value for *{{use_legacy_dataset}}* is False, whereas the implementation has a value of True.
It looks to have been implemented and reviewed pretty carelessly.
