+Pandas APIs on Spark targets Python data scientists. We want to stick to the
convention that users are already familiar with as much as possible. Here are
some examples:
-- Function names and parameters use snake_case, rather than CamelCase. This is
different from PySpark's design. For example, Koalas has `to_pandas()`, whereas
PySpark has `toPandas()` for converting a DataFrame into a pandas DataFrame. In
limited cases, to maintain compatibility with Spark, we also provide Spark's
variant as an alias.
