benibus opened a new issue, #36036: URL: https://github.com/apache/arrow/issues/36036
### Describe the enhancement requested There's currently an active proposal to add a half-float logical type to the Parquet spec here: https://github.com/apache/parquet-format/pull/184. Following the discussion in the PR/issue, the general consensus was that we should go ahead and implement support for the type before moving forward with a vote. To summarize, this would currently entail adding a float16 logical type (based on a 2-byte fixed-size binary physical type) and implementing read/write support. We also want to ensure that its ordering requirements are consistent with the native floating point types, min/max values are properly handled in `Statistics`, etc. ### Component(s) C++, Parquet -- This is an automated message from the Apache Git Service.
