   Without knowing what your data looks like it is hard to say how to better partition it. But you can raise the maximum number of partitions via `max_partitions` which defaults to 1024 or you could just limit the number of rows per file if you don't have a more specific partitioning scheme with `max_rows_per_file`:

   Feel free to close the issue if this answers your question.
