🚀

You can now export dataframes into multiple files, using to_csv_folder / to_parquet_folder.

Exporting your data in one huge file is often a big problem for the next steps in your workflow. Terality now offers the possibility to export a dataframe into multiple files, with two extra methods to the pandas API: to_csv_folder and to_parquet_folder. 

The number of files can be specified in several ways:: the number of files, the number of rows per file, or the in-memory size per file.
