[jira] [Commented] (ARROW-16119) [Python] Deprecate the legacy ParquetDataset custom python-based implementation

["Joris Van den Bossche (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARROW-16119?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17545457#comment-17545457 ] 

Joris Van den Bossche commented on ARROW-16119:
-----------------------------------------------

The ParquetDataset() constructor itself still defaults to {{use_legacy_dataset=True}} (although using specific attributes or keywords related to that will raise a warning). So a next step will be to actually deprecate passing that and switching the default, and then only afterwards we can remove the code.
