jonkeane opened a new issue, #43349:
URL: https://github.com/apache/arrow/issues/43349
### Describe the bug, including details regarding any error messages,
version, and platform.
On dev, here is a reprex:
```
arrow::as_arrow_table(
readr::read_csv(readr::readr_example("chickens.csv"), lazy = TRUE),
sink = tempfile(fileext=".parquet")
)
#> Rows: 5 Columns: 4
#> ── Column specification
────────────────────────────────────────────────────────
#> Delimiter: ","
#> chr (3): chicken, sex, motto
#> dbl (1): eggs_laid
#>
#> ℹ Use `spec()` to retrieve the full column specification for this data.
#> ℹ Specify the column types or set `show_col_types = FALSE` to quiet this
message.
#> Error in Table__from_dots(dots, schema, option_use_threads()): No Set_elt
found for ALTSTRING class [class: vroom_chr, pkg: vroom]
```
This wasn't a problem in our last release:
```
arrow::as_arrow_table(
readr::read_csv(readr::readr_example("chickens.csv"), lazy = TRUE),
sink = tempfile(fileext=".parquet")
)
#> Rows: 5 Columns: 4
#> ── Column specification
────────────────────────────────────────────────────────
#> Delimiter: ","
#> chr (3): chicken, sex, motto
#> dbl (1): eggs_laid
#>
#> ℹ Use `spec()` to retrieve the full column specification for this data.
#> ℹ Specify the column types or set `show_col_types = FALSE` to quiet this
message.
#> Table
#> 5 rows x 4 columns
#> $chicken <string>
#> $sex <string>
#> $eggs_laid <double>
#> $motto <string>
#>
#> See $metadata for additional Schema metadata
