paleolimbot opened a new pull request, #14518:
URL: https://github.com/apache/arrow/pull/14518
This PR enables the following to work:
``` r
library(arrow, warn.conflicts = FALSE)
#> Some features are not enabled in this build of Arrow. Run `arrow_info()`
for more information.
register_scalar_function(
"times_32",
function(context, x) x * 32.0,
int32(),
float64(),
auto_convert = TRUE
)
record_batch(a = 1:1000) |>
dplyr::mutate(b = times_32(a)) |>
as_record_batch_reader() |>
head(11) |>
as_arrow_table()
#> Table
#> 11 rows x 2 columns
#> $a <int32>
#> $b <double>
```
(normally this isn't a problem because you should really call `head()`
before `as_record_batch_reader()`, which communicates the top-k-ness of the
query to the ExecPlan rather than relying on abandoning a RecordBatchReader;
however, it still should work!)
