Joris Van den Bossche commented on ARROW-13074:
-----------------------------------------------
[~ldacey] the current PR is only about the {{ParquetDataset}} class, so for
reading parquet, not for writing parquet
Let's keep discussion about {{partition_filename_cb}} for ARROW-12365 (the
issue [~ldacey] created specifically for that topic)
> [Python] Start with deprecating ParquetDataset custom attributes
> ----------------------------------------------------------------

> Key: ARROW-13074
> URL: https://issues.apache.org/jira/browse/ARROW-13074
> Project: Apache Arrow
> Issue Type: Improvement
> Components: Python
> Reporter: Joris Van den Bossche
> Assignee: Joris Van den Bossche
> Priority: Major
> Labels: pull-request-available
> Fix For: 5.0.0
>
> Time Spent: 40m
> Remaining Estimate: 0h
>
> As a first step for ARROW-9720, we should start with deprecating
> attributes/methods of {{pq.ParquetDataset}} that we would definitely not keep
> / are conflicting with the "dataset API".
> I am thinking of the {{pieces}} attribute (and the {{ParquetDatasetPiece}}
> class), the {{partitions}} attribute (and the {{ParquetPartitions}} class).
> In addition, some of the keywords are also exposed as properties (memory_map,
> read_dictionary, buffer_size, fs), and could be deprecated.
