```
fails with:
```
Error: ArrowError(NotYetImplemented("not yet implemented: Map(Field { name:
\"entries\", data_type: Struct([Field { name: \"key\", data_type: Utf8,
nullable: false, dict_id: 0, dict_is_ordered: false, metadata: {} }, Field {
name: \"value\", data_type: Float32, nullable: true, dict_id: 0,
dict_is_ordered: false, metadata: {} }]), nullable: false, dict_id: 0,
dict_is_ordered: false, metadata: {} }, false)"), None)
