> [C++][Dataset][Python] Improve ParquetFileFragment serialization
> ----------------------------------------------------------------
>
> Key: ARROW-10435
> URL: https://issues.apache.org/jira/browse/ARROW-10435
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++
> Affects Versions: 2.0.0
> Reporter: Ben Kietzman
> Priority: Major
> Labels: dataset
> Fix For: 8.0.0
>
>
> After ARROW-10131 {{ParquetFileFragment}} wraps a FileMetaData, from which
> all its properties are queried. FileMetaData is emminently serializable, so
> when pickling a fragment with pre-loaded metadata it would save redundant IO
> to just serialize the metadata. (An unpickled fragment would then also have
> pre-loaded metadata.)
