[jira] [Comment Edited] (ARROW-13074) [Python] Start with deprecating ParquetDataset custom attributes

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

------------------------------------------------------------------------

[~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; there was also discussion at ARROW-10695 on this topic)

> 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.
