Summary: [Python] Filename-based partitioning scheme (was: Filename-based
partitioning scheme)
> [Python] Filename-based partitioning scheme
> -------------------------------------------
>
> Key: ARROW-14176
> URL: https://issues.apache.org/jira/browse/ARROW-14176
> Project: Apache Arrow
> Issue Type: Wish
> Components: Python
> Reporter: Cédric Hernalsteens
> Priority: Major
>
> This originates from [this SO
> question|[https://stackoverflow.com/questions/69379083/read-a-partitioned-parquet-dataset-from-multiple-files-with-pyarrow-and-add-a-pa].]
> The idea is to have a portioning scheme that would allow to construct a
> primary key from the filename.
> Let's say that one is trying to read `/data-N.parquet` where `N` is an
> integer. That information should go in a primary key for later reference.
> This is quite similar to have the files laid-out like this :
> `/N/data.parquet` so I imagine this is technically feasible.
