Process part of the columns, instead of giving an error?
When the number of columns is above 1000, we don't process the split. See https://github.com/huggingface/datasets-server/issues/1143.

Should we instead "truncate", and only process the first 1000 columns, and give a hint to the user that only the first 1000 columns were used?
