[jira] [Closed] (ARROW-2685) [C++] Implement kernels for in-place sorting of fixed-width contiguous arrays

     [ https://issues.apache.org/jira/browse/ARROW-2685?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Wes McKinney closed ARROW-2685.
-------------------------------
    Fix Version/s:     (was: 2.0.0)
       Resolution: Won't Fix

Since we have SortToIndices and Arrow arrays have immutable semantics, this should be solved a different way

> See discussion in https://github.com/apache/arrow/issues/2112. A kernel may want to throw if the memory being sorted is shared (in which case the user should copy, then sort)
> Sorting of chunked data is a more complex topic so that's out of scope for this task
