Hi
I asked this issue on mapping one entry to multiple entries with huggingface dataset library:

https://github.com/huggingface/datasets/issues/2767

Not sure if this is better to be asked here, please let me know to close the issue in the repo, or here.

thank you for your kind response and assistance on how one can model this with huggingface datasets.

really appreciate your response @lhoestq
