[GitHub] [arrow] zeroshade opened a new issue, #34171: [Go][Compute] Add kernel for "unique" function

["zeroshade (via GitHub)" <gi...@apache.org>]

zeroshade opened a new issue, #34171:
URL: https://github.com/apache/arrow/issues/34171

   ### Describe the enhancement requested
   
   Following up on #33466, in order to implement direct and efficient handling of dictionary arrays to/from parquet without having to expand them out, we first need to implement a compute "unique" function kernel so we can easily compute the statistics on the dictionary like max/min. In theory it would be more efficient to do this with a "min_max" kernel itself, but that would take longer and be more involved to create at the moment. 
   
   In the meantime, it's still useful to be able to compute a uniquified version of an Arrow array.
   
   ### Component(s)
   
   Go
