As far as I can tell, yes only struct arrays take elements as a dictionary,
not a map array.
Just for completeness, though, I wanted to mention that you can use
`dict.items()` to get a list of tuples. I realize that I don't know how complex
your actual structure is or how many you have, etc; so, this is just if you
have a stronger preference for map arrays than struct arrays.
```python
# tags_ref is a generator, so maybe not too much performance impact?
# could also consider wrapping the dict in a class that delegates all
calls except when accessing 'tags'?
# some_row = {'id': 1, 'tags': {'tag1': 'value1', 'tag2': 'value2'}}
tags_ref = (
{
'id' : some_row.get('id')
,'tags': list(some_row.get('tags').items())
}
for some_row in tags_updated
)
table = Table.from_pylist(mapping=list(tags_ref), schema=pyarrow_schema)
```
