    Component/s: Python

> [Python] Expose JSON schema inference to Python API
> ---------------------------------------------------
>
>                 Key: ARROW-12588
>                 URL: https://issues.apache.org/jira/browse/ARROW-12588
>             Project: Apache Arrow
>          Issue Type: Improvement
>          Components: Python
>            Reporter: Piotr Żelasko
>            Priority: Minor
>
> When using `pyarrow.json.read_json()`, the schema is automatically inferred. 
> It would be useful to infer the schema from a json that is already loaded in 
> memory (i.e. possibly a list of dicts in Python).
