> Currently, when {{chunk_size}} is not given in {{write_parquet()}} it defaults to 1 chunk of all of the rows in the table. This could be fine for smallish numbers of rows, but when we have lots of rows, we want files that contain a decent number of row groups.
> It looks like this was added in https://github.com/apache/arrow/pull/5451 and wasn't discussed there, so this default might not be intentional.
