Nicola Crane created ARROW-14989:
------------------------------------
Summary: [R] Update num_rows methods to output doubles not
integers to prevent integer overflow
Key: ARROW-14989
URL: https://issues.apache.org/jira/browse/ARROW-14989
Project: Apache Arrow
Issue Type: Improvement
Components: R
Reporter: Nicola Crane
In cases where Arrow objects are particularly large, this can result in an
integer overflow when returning their size. See discussion on
https://github.com/apache/arrow/pull/11783 for more details of a possible
solution.
{code:r}
library(arrow)
test_array1 <- Array$create(raw(2^31 - 1))
test_array2 <- Array$create(raw(1))
big_chunked <- chunked_array(test_array1, test_array2)
big_table <- Table$create(col = big_chunked)
big_table$num_rows
# NA
