Joris Van den Bossche commented on ARROW-12588:
-----------------------------------------------
Good to hear that it's working!
We could certainly have better documentation regarding this, i.e. what
approaches can be used when having in-memory json like data / dict, and you
want to convert this to a pyarrow Table. I agree that using {{pa.array(..)}} is
not necessarily the first thing you would think about.

> 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).
