amol- opened a new issue, #44446: URL: https://github.com/apache/arrow/issues/44446
### Describe the enhancement requested In various conditions it would be helpful to be able to generate boolean masks that point to specific indices of an array. For example it can be combined with `if_else` compute functions to merge two arrays by picking exactly which rows should come from each of one the arrays. Or combined with `replace_with_mask` to set rows in an array. At the moment there is no easy way to create such a mask ### Component(s) C++, Python -- This is an automated message from the Apache Git Service.
