Bjørn Jørgensen updated SPARK-41553:
------------------------------------
Description:
num_files has been deprecated and might be removed in a future version. "
"Use DataFrame.spark.repartition instead.",
The num_files argument doesn't manage the number of files, but specifying the
partition number.
was:
Functions have this signature.
def to_json(
(..)
num_files: Optional[int] = None,
.. note:: pandas-on-Spark writes JSON files into the directory, `path`, and
writes
multiple `part-...` files in the directory when `path` is specified.
This behavior was inherited from Apache Spark. The number of files can
be controlled by `num_files`.
if num_files is not None:
warnings.warn(
"`num_files` has been deprecated and might be removed in a future version. "
"Use `DataFrame.spark.repartition` instead.",
FutureWarning,
)
I will change num_files to repartition
> Fix the documentation for num_files
