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 -- This is an automated message from the Apache Git Service.
