andrei-ionescu opened a new issue, #3322:
URL: https://github.com/apache/arrow-rs/issues/3322
**Describe the bug**
The pretty print implementation for Map is missing.
```
Error: ArrowError(InvalidArgumentError("Pretty printing not implemented for
Map(Field { name: \"map\", data_type: Struct([Field { name: \"key\", data_type:
Utf8, nullable: false, dict_id: 0, dict_is_ordered: false, metadata: {} },
Field { name: \"value\", data_type: Utf8, nullable: true, dict_id: 0,
dict_is_ordered: false, metadata: {} }]), nullable: false, dict_id: 0,
dict_is_ordered: false, metadata: {} }, false) type"))
```
**To Reproduce**
```
let df = ctx.read_parquet(glob_path, ParquetReadOptions::default()).await?;
df.show().await?
```
**Expected behavior**
To print either the map's content or a hash representation of that map.
**Additional context**
This is in the context of using DataFusion and loading some parquet files
containing Maps.
The code that does the pretty print is here:
