orgadish opened a new issue, #38031: URL: https://github.com/apache/arrow/issues/38031
### Describe the enhancement requested Per the documentation, `col_select` is currently not supported in `arrow::open_csv_dataset` and it is recommended to "instead, subset columns after dataset creation". This approach doesn't work, however, when the files don't share the total schema. Often, though, I may only care about a subset of columns which I know are shared by all the files, even if random other columns have been added in. It would be great if there was a way to specify that columns outside the schema should be ignored, or to enable `col_select`. ### Component(s) R -- This is an automated message from the Apache Git Service.
