Hello Alex.
Thanks for welcoming (even if I contributed once something like 10 years ago :smile:).
You are right, I forgot to mention it was required by Tableau Hyper API as you can download it [here](https://pypi.org/project/tableauhyperapi/0.0.21200/#files). This is shipped with a python package to read/write .hyper DB files (see [doc](https://tableau.github.io/hyper-db/docs/guides/sql_commands) on how to that in a few lines of python).
Don't ask why I'm using python windows on a linux machine :slight_smile: We work with an ETL tool that integrates this as a way to import/export files for Tableau (which is also an ETL tool).
Cheers.
