             Summary: [Python] Deprecate no-longer supported keywords in parquet.write_to_dataset
                 Key: ARROW-16122
                 URL: https://issues.apache.org/jira/browse/ARROW-16122
             Project: Apache Arrow
          Issue Type: Sub-task
          Components: Python
            Reporter: Joris Van den Bossche
             Fix For: 8.0.0


Currently, the {{pq.write_to_dataset}} function also had a {{use_legacy_dataset}} keyword, but we should:

1) in case of {{use_legacy_dataset=True}}, ensure we raise deprecation warnings for all keywords that won't be supported in the new implementation (eg {{partition_filename_cb}})
2) raise a deprecation warning for {{use_legacy_dataset=True}}, and/or already switch the default?
