Thank you for opening a Pull Request! Before submitting your PR, there are a few things you can do to make sure it goes smoothly:

  • Make sure to open an issue as a bug/issue before writing your code! That way we can discuss the change, evaluate designs, and agree on the general idea
  • Ensure the tests and linter pass
  • Code coverage does not decrease (if any source code was changed)
  • Appropriate docs were updated (if necessary)

Fixes #265 馃

I'm a bit surprised to see this test passing. I guess we still have some code that falls back to the default pandas parquet rendering?

Can you look into if we can remove that code path?

Related: We should be able to simplify this docstring now:

parquet_compression (Optional[str]):
[Beta] The compression method to use if intermittently
serializing ``dataframe`` to a parquet file.
If ``pyarrow`` and job config schema are used, the argument
is directly passed as the ``compression`` argument to the
underlying ``pyarrow.parquet.write_table()`` method (the
default value "snappy" gets converted to uppercase).
https://arrow.apache.org/docs/python/generated/pyarrow.parquet.write_table.html#pyarrow-parquet-write-table
If either ``pyarrow`` or job config schema are missing, the
argument is directly passed as the ``compression`` argument
to the underlying ``DataFrame.to_parquet()`` method.

I'd like to see us add "pyarrow" to the "pandas" extras now, since it's needed for both uploads and downloads to dataframe.

We can maybe refactor the pyarrow >=1.0.0,<2.0dev string into a variable since it's going to appear 3 times in setup.py now too

@tswast OK, this was a bit more involved than I expected at the beginning. Here goes my second attempt.
