Ian Cook created ARROW-12087:
--------------------------------
Summary: [C++] Fix sort_indices, array_sort_indices timestamp
support discrepancy
Key: ARROW-12087
URL: https://issues.apache.org/jira/browse/ARROW-12087
Project: Apache Arrow
Issue Type: Bug
Components: C++
Reporter: Ian Cook
{{sort_indices}} supports sorting by timestamp arrays, but
{{array_sort_indices}} does not. Here's some example R code to demonstrate this
(but this example code depends on ARROW-11703 to run):
{code:java}
tbl <- tibble::tibble(
dttm = lubridate::ymd_hms(c("2021-01-01 00:00:00", "1900-01-01 00:00:00")),
)
rb <- arrow::record_batch(tbl)
# this fails:
arrow:::call_function(
"array_sort_indices",
rb$dttm,
options = list(order = F)
)
## Error: NotImplemented: Function array_sort_indices has no kernel matching
input types (array[timestamp[us, tz=UTC]])
# this fails
arrow:::call_function(
"sort_indices",
rb,
options = list(names = "dttm", orders = 0L)
)
## Error: NotImplemented: Function array_sort_indices has no kernel matching
input types (array[timestamp[us, tz=UTC]])
# this succeeds
arrow:::call_function(
"sort_indices",
rb,
options = list(names = c("dttm", "dttm"), orders = 0L)
)
## Array
## <uint64>
## [
## 1,
## 0
## ]{code}
