>             Project: Parquet
>          Issue Type: Improvement

> h2. DESCRIPTION
>  
> I'm wondering if there's any interest in supporting Arrow's {{float16}} type in Parquet.
> There seem to be one or two {{float16}} / {{halffloat}} tickets here (e.g., PARQUET-1403) but nothing that speaks to adding half-float support to Parquet in-general.
>  
> h2. PLANS
> I'm able to spend some time on this, if someone points me  in the right direction.
>  
>  # Add the {{HALFFLOAT}} or {{FLOAT16}} enum (any preferred naming convention?) to [https://github.com/apache/parquet-format/blob/master/src/main/thrift/parquet.thrift#L32]
>  # Add {{HALFFLOAT}} to {{org.apache.parquet.schema.PrimitiveType}}
>  # Add {{HALFFLOAT}} support to {{org.apache.parquet.arrow.schema.SchemaConverter}}
>  # Add encoding for new type at {{org.apache.parquet.column.Encoding}}
>  # ??
> If anyone has any interest in this, pointers, or comments, they would be greatly appreciated!
