Matteo Sostero updated ARROW-11922:
-----------------------------------
Description:
The old R `feather` package had a function calledÂ
{{feather::feather_metadata()}} that allowed to read column names and types
from feather files on disk, without opening them. This was useful to select
only specific columns when loading a feather file in R with
{{read_feather(path, columns = c(...)}}
Apparently [there is no direct replacement for this function in
arrow|https://stackoverflow.com/a/66540589/926810]. Can one be implemented?
