=================
It is currently possible to write an Arrow :class:`pyarrow.Table` to
-CSV by going through pandas. Arrow doesn't currently provide an optimized
-code path for writing to CSV.
+a CSV file using the :func:`pyarrow.csv.write_csv` function
.. testcode::
+ arr = pa.array(range(100))
table = pa.Table.from_arrays([arr], names=["col1"])
- table.to_pandas().to_csv("table.csv", index=False)
+
+ import pyarrow.csv
+ pa.csv.write_csv(table, "table.csv",
+ write_options=pa.csv.WriteOptions(include_header=True))
Review comment:
I saw, that's why I moved the `arr = pa.array(range(100))` into the test
code, so that it's more explicit.
