Hi community, Hope this email finds you well. Can folk guide how to write hive partitioning with partitioning keys *in the file*? Right now only the subset of the data will be written.
Both Python pyarrow.dataset.wite_dataset(...) <https://arrow.apache.org/cookbook/py/io.html#writing-partitioned-datasets> and the C++ FileSystemDatasetWriteOptions(...) <https://arrow.apache.org/docs/cpp/dataset.html#reading-and-writing-partitioned-data> have this behavior. I failed to find how to change when reading the doc. If it's not possible, which file should I check to extend it in the C++ code? I can contribute the change to the github trunk.
