> @wgtmac, I don't think we automatically deploy snapshot versions. And, we
will need a final release of parquet-format anyway, before we can get this one
merged.
OK, then let's wait until format v2.10 is released. Once two PoC
implementations of https://github.com/apache/parquet-format/pull/197 have been
finished, I will kick off the release process.

> Key: PARQUET-1647
> URL: https://issues.apache.org/jira/browse/PARQUET-1647
> Project: Parquet
> Issue Type: Improvement
> Components: parquet-format, parquet-thrift
> Reporter: The Alchemist
> Priority: Minor

> 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!
